Concurrently, computational imaging leverages algorithms to reconstruct images from optically processed signals, overcoming the limitations of traditional imaging systems. This Perspective explores the synergistic integration of metaoptics and computational imaging, “metaoptic computational imaging”, which combines the physical wavefront shaping ability of metasurfaces with advanced computational algorithms to enhance imaging performance beyond conventional limits. We discuss how metaoptic computational imaging addresses the inherent limitations of single-layer metasurfaces in achieving multifunctionality without compromising efficiency. By treating metasurfaces as physical preconditioners and codesigning them with reconstruction algorithms through end-to-end (inverse) design, it is possible to jointly optimize the optical hardware and computational software. Advanced applications and new frontiers in the field enabled by metaoptic computational imaging are highlighted, including phase imaging and quantum state measurement."}],"fulldoi":"https://doi.org/10.1021/acsphotonics.4c02266","day":"13","date_updated":"2026-04-27T07:12:34Z","status":"public","month":"02","language":[{"iso":"eng"}],"article_processing_charge":"No","type":"journal_article","volume":12,"date_created":"2026-03-30T12:22:47Z","date_published":"2025-02-13T00:00:00Z","title":"Metaoptic computational imaging","publication_identifier":{"eissn":["2330-4022"]},"_id":"21530","oa_version":"None","author":[{"last_name":"Roques-Carmes","first_name":"Charles","full_name":"Roques-Carmes, Charles","id":"e2e68fc9-6505-11ef-a541-eb4e72cc3e82"},{"full_name":"Wang, Kai","last_name":"Wang","first_name":"Kai"},{"last_name":"Yang","full_name":"Yang, Yuanmu","first_name":"Yuanmu"},{"last_name":"Majumdar","first_name":"Arka","full_name":"Majumdar, Arka"},{"full_name":"Lin, Zin","last_name":"Lin","first_name":"Zin"}],"scopus_import":"1","publication":"ACS Photonics"},{"date_updated":"2026-04-27T08:42:39Z","day":"28","fulldoi":"https://doi.org/10.1021/acsphotonics.5c00813","abstract":[{"lang":"eng","text":"Entanglement is a unique feature of quantum mechanics. In coupled systems of light and matter, entanglement manifests itself in the linear superposition of multipartite quantum states (e.g., parametrized by the multiple spatial, spectral, or temporal degrees of freedom of a light field). In bipartite systems, the Schmidt decomposition provides a modal decomposition of the entanglement structure over independent, separable states. Although ubiquitous as a mathematical tool to describe and measure entanglement, there exists no general efficient experimental method to decompose a bipartite quantum state onto its Schmidt modes. Here, we propose a method that relies on bipartite self-configuring optics that automatically ``learns'' the Schmidt decomposition of an arbitrary pure quantum state. Our method is agnostic to the degrees of freedom over which quantum entanglement is distributed and can reconstruct the Schmidt modes and values by variational optimization of the network's output powers or coincidences. We illustrate our method with numerical examples of spectral entanglement analysis for biphotons generated via spontaneous parametric down conversion and provide experimental guidelines for its realization, including the influence of losses and impurities. Our method provides a versatile and scalable way of analyzing entanglement in bipartite integrated quantum photonic systems.

Here, we present a three-bin energy-resolved X-ray imaging framework based on a three-layer multicolor scintillator used in conjunction with a physics-aware image postprocessing algorithm. The multicolor scintillator is able to preserve X-ray energy information through the combination of emission wavelength multiplexing and energy-dependent isolation of X-ray absorption in specific layers. The dominant emission color and the radius of the spot measured by the detector are used to infer the incident X-ray energy based on prior knowledge of the energy-dependent absorption profiles of the scintillator stack. Through ab initio Monte Carlo simulations, we show that our approach can achieve an energy reconstruction accuracy of 49.7%, which is only 2% below the maximum accuracy achievable with realistic scintillators.

Here, motivated by recent advances in using non-Hermitian photonics and gain/loss engineering to enable non-reciprocal light transport, we explore how the interplay between non-Hermiticity and optical nonlinearity leads to a fundamentally new regime of nonlinear frequency conversion. We show how non-Hermitian coupling between discrete frequency modes can result in non-reciprocal flow of energy in a frequency dimension, closely resembling the non-Hermitian skin effect (NHSE). Applying our theory to a multimode nonlinear cavity supporting cascaded nonlinear processes, we demonstrate chiral energy flow in a frequency dimension, leading to long-range frequency shifts of quasi-continuous wave sources, shaped frequency combs robust to defects and disorder, terahertz (THz) generation far exceeding the Manley-Rowe limit, and nonlinear multimodal limit cycles for multi-frequency pump-probe spectroscopy.","lang":"eng"}],"day":"14","date_updated":"2026-04-27T10:06:42Z","date_created":"2026-03-30T12:22:47Z","volume":16,"license":"https://creativecommons.org/licenses/by-nc-nd/4.0/","DOAJ_listed":"1","tmp":{"name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","image":"/images/cc_by_nc_nd.png","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","short":"CC BY-NC-ND (4.0)"},"article_processing_charge":"No","type":"journal_article"},{"month":"08","language":[{"iso":"eng"}],"status":"public","day":"14","date_updated":"2026-04-27T08:37:35Z","fulldoi":"https://doi.org/10.1038/s41467-025-63035-8","abstract":[{"text":"Observing non-classical properties of light is a long-standing interest to advance a wide range of quantum applications. Optical cavities are essential to generate and manipulate non-classical light. However, detecting changes in cavity properties induced by the quantum state remains a critical challenge in the optical domain due to the weak material nonlinearity. Here, we propose a framework for observing the dynamics of quantum states generated inside nonlinear optical cavities. We leverage the symmetry-breaking process of a bistable system, which is highly sensitive to the initial state, enabling detection of quantum state displacement through an asymmetric equilibrium of a macroscopic observable. With a nonlinear response at the single photon level, our approach directly imprints the cavity field distribution onto the statistics of bistable cavity steady-states. We experimentally demonstrate our approach in a degenerate optical parametric oscillator, generating and reconstructing different quantum states. As a validation, we reconstruct the Husimi Q function of the cavity squeezed vacuum state. In addition, we observe the evolution of the quantum vacuum state inside the cavity as it undergoes phase-sensitive amplification. By enabling generation and measurement of quantum states in a single nonlinear optical cavity, our method paves a way for studying exotic dynamics of quantum optical states in nonlinear driven-dissipative systems.","lang":"eng"}],"date_created":"2026-03-30T12:22:47Z","volume":16,"tmp":{"name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","image":"/images/cc_by_nc_nd.png","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","short":"CC BY-NC-ND (4.0)"},"article_processing_charge":"No","type":"journal_article","DOAJ_listed":"1","publication_identifier":{"eissn":["2041-1723"]},"title":"Observing the dynamics of quantum states generated inside nonlinear optical cavities","arxiv":1,"date_published":"2025-08-14T00:00:00Z","publication":"Nature Communications","scopus_import":"1","author":[{"first_name":"Seou","full_name":"Choi, Seou","last_name":"Choi"},{"first_name":"Yannick","last_name":"Salamin","full_name":"Salamin, Yannick"},{"first_name":"Charles","last_name":"Roques-Carmes","id":"e2e68fc9-6505-11ef-a541-eb4e72cc3e82","full_name":"Roques-Carmes, Charles"},{"first_name":"Jamison","last_name":"Sloan","full_name":"Sloan, Jamison"},{"last_name":"Horodynski","full_name":"Horodynski, Michael","first_name":"Michael"},{"full_name":"Soljačić, Marin","last_name":"Soljačić","first_name":"Marin"}],"external_id":{"pmid":["40813397"],"arxiv":["2412.01772"]},"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1038/s41467-025-63035-8"}],"oa_version":"Published Version","_id":"21543","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"ista":"Choi S, Salamin Y, Roques-Carmes C, Sloan J, Horodynski M, Soljačić M. 2025.

Taming this noise is pivotal to a wide range of applications, both classical and quantum. Here we demonstrate the creation of intense light with quantum levels of noise even when starting from inputs with large amounts of excess noise. In particular, we demonstrate how intense squeezed light with intensities approaching 0.1 TW cm−2, but noise at or below the shot-noise level, can be produced from noisy inputs associated with high-power amplified laser sources (an overall noise reduction of 30-fold). On the basis of a new theory of quantum noise in multimode systems, we show that the ability to generate quantum light from noisy inputs results from multimode quantum correlations, which maximally decouple the output light from the dominant noise channels in the input light. As an example, we demonstrate this effect for femtosecond pulses in nonlinear fibres, but the noise-immune correlations that enable our results are generic to many other nonlinear systems in optics and beyond."}],"fulldoi":"https://doi.org/10.1038/s41566-025-01677-2","day":"14","date_updated":"2026-04-27T09:37:19Z","external_id":{"arxiv":["2311.05535"]},"author":[{"last_name":"Zia Uddin","full_name":"Zia Uddin, Shiekh","first_name":"Shiekh"},{"last_name":"Rivera","first_name":"Nicholas","full_name":"Rivera, Nicholas"},{"first_name":"Devin","full_name":"Seyler, Devin","last_name":"Seyler"},{"first_name":"Jamison","full_name":"Sloan, Jamison","last_name":"Sloan"},{"full_name":"Salamin, Yannick","first_name":"Yannick","last_name":"Salamin"},{"id":"e2e68fc9-6505-11ef-a541-eb4e72cc3e82","full_name":"Roques-Carmes, Charles","first_name":"Charles","last_name":"Roques-Carmes"},{"first_name":"Shutao","last_name":"Xu","full_name":"Xu, Shutao"},{"last_name":"Sander","full_name":"Sander, Michelle Y.","first_name":"Michelle Y."},{"first_name":"Ido","last_name":"Kaminer","full_name":"Kaminer, Ido"},{"full_name":"Soljačić, Marin","first_name":"Marin","last_name":"Soljačić"}],"publication":"Nature Photonics","scopus_import":"1","_id":"21544","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2311.05535"}],"oa_version":"Preprint","title":"Noise-immune quantum correlations of intense light","publication_identifier":{"issn":["1749-4885"],"eissn":["1749-4893"]},"arxiv":1,"date_published":"2025-05-14T00:00:00Z"},{"citation":{"short":"D.

As advances in AI lead to growing computing demands, photonic computing has gained considerable attention as an appealing candidate. Nonetheless, there are substantial technical challenges in the scaling up of integrated photonics systems to realize these advantages, such as ensuring consistent performance gains in upscaled integrated device clusters, establishing standard designs and verification processes for complex circuits, as well as packaging large-scale systems. These obstacles arise primarily because of the relative immaturity of integrated photonics manufacturing and the scarcity of advanced packaging solutions involving photonics. Here we report a large-scale integrated photonic accelerator comprising more than 16,000 photonic components. The accelerator is designed to deliver standard linear matrix multiply–accumulate (MAC) functions, enabling computing with high speed up to 1 GHz frequency and low latency as small as 3 ns per cycle. Logic, memory and control functions that support photonic matrix MAC operations were designed into a cointegrated electronics chip. To seamlessly integrate the electronics and photonics chips at the commercial scale, we have made use of an innovative 2.5D hybrid advanced packaging approach. Through the development of this accelerator system, we demonstrate an ultralow computation latency for heuristic solvers of computationally hard Ising problems whose performance greatly relies on the computing latency.","lang":"eng"}],"day":"09","date_updated":"2026-04-27T08:38:44Z","date_created":"2026-03-30T12:22:47Z","volume":640,"tmp":{"name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","image":"/images/cc_by_nc_nd.png","legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","short":"CC BY-NC-ND (4.0)"},"type":"journal_article","article_processing_charge":"No","publisher":"Springer Nature","OA_type":"hybrid","intvolume":" 640","extern":"1","pmid":1,"article_type":"original","OA_place":"publisher","oa":1,"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"ama":"Hua S, Divita E, Yu S, et al.

Here we study a model of parametrically driven cavity quantum electrodynamics (QED) for enhancing light-matter interaction while subjected to a finite-bandwidth squeezed vacuum drive. Our method is capable of unveiling the effect of relative bandwidth as well as squeezing required to observe the anticipated anticrossing spectrum and enhanced cooperativity without the ideal squeezed bath assumption. Furthermore, we analyze the practicality of said models when including intrinsic photon loss due to resonator imperfection.

Waveguide quantum electrodynamics is a promising platform for achieving this, as it hosts infinite-range interactions and decoherence-free subspaces of quantum emitters. However, as coherent interactions between emitters are typically washed out in the wavelength-spacing regime hosting decoherence-free states, coherent control over the latter becomes limited, and many-body Hamiltonians in this important regime remain out of reach. Here we show that by incorporating emitter arrays with nonlinear waveguides hosting parametric gain, we obtain a unique class of many-body interaction Hamiltonians with coupling strengths that increase with emitter spacing, and persist even for wavelength-spaced arrays. We then propose to use these Hamiltonians to coherently generate decoherence-free states directly from the ground state, using only global squeezing drives, without the need for local addressing of individual emitters. Interestingly, we find that the dynamics approaches a unitary evolution in the limit of weak intrawaveguide squeezing, and we discuss potential experimental realizations of this effect. Our results pave the way towards coherent control protocols in waveguide quantum electrodynamics, with applications including quantum computing, simulation, memory, and nonclassical light generation."}],"day":"21","date_updated":"2026-04-27T10:32:06Z"},{"OA_place":"publisher","oa":1,"article_number":"L022056","article_type":"letter_note","publisher":"American Physical Society","issue":"2","intvolume":" 7","OA_type":"gold","extern":"1","quality_controlled":"1","ddc":["530"],"year":"2025","doi":"10.1103/physrevresearch.7.l022056","citation":{"chicago":"Gu, Alex, Jamison Sloan, Charles Roques-Carmes, Seou Choi, Eric I.

Understanding how quantum states may influence the behavior of nonlinear dynamic systems may open new avenues in controlling light-matter interactions. To explore this issue, we analyze the sensitivity of a fundamental quantum optical process – parametric oscillation – to quantum initializations. Focusing on optical parametric oscillators (OPOs), we demonstrate that the quantum statistics of arbitrary initial states are imprinted in the early-stage dynamics and can persist in the steady-state probabilities. We derive the “quantum sensitivity” of parametric oscillators, linking the initial quantum state to the system's steady-state outcomes, highlighting how losses and parametric gain govern the system's quantum sensitivity. Moreover, we show that these findings extend beyond OPOs to a broader class of nonlinear systems, including Josephson junction based superconducting circuits. Our work opens the way to a new class of experiments that can test the sensitivity of macroscopic systems to quantum initial conditions and offers a pathway for controlling systems with quantum degrees of freedom."}],"date_updated":"2026-04-27T10:37:53Z","day":"06","status":"public","month":"06","language":[{"iso":"eng"}]},{"scopus_import":"1","author":[{"id":"e2e68fc9-6505-11ef-a541-eb4e72cc3e82","last_name":"Roques-Carmes","full_name":"Roques-Carmes, Charles","first_name":"Charles"},{"last_name":"Karnieli","full_name":"Karnieli, Aviv","first_name":"Aviv"},{"full_name":"Miller, David A.B.","first_name":"David A.B.","last_name":"Miller"},{"full_name":"Fan, Shanhui","last_name":"Fan","first_name":"Shanhui"}],"publication":"2025 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference","_id":"21566","conference":{"start_date":"2025-06-23","end_date":"2025-06-27","name":"CLEO: Conference on Lasers and Electro-Optics Europe & European Quantum Electronics","location":"Munich, Germany"},"oa_version":"None","publisher":"IEEE","publication_identifier":{"eissn":[" 2833-1052 "],"eisbn":["9798331512521"]},"title":"Variational optical processors","OA_type":"closed access","extern":"1","date_published":"2025-07-01T00:00:00Z","doi":"10.1109/cleo/europe-eqec65582.2025.11109871","year":"2025","date_created":"2026-03-30T12:22:47Z","quality_controlled":"1","type":"conference","article_processing_charge":"No","status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"07","language":[{"iso":"eng"}],"citation":{"short":"C.

Nanophotonic scintillators are a promising platform to control and enhance spontaneous light emission in scintillators. Mechanisms of light control and generation enhancement with nanophotonic scintillators include (1) angular light emission control and outcoupling enhancements with surface-patterned scintillators [1, 2]; and (2) enhancement of the rate of spontaneous emission by volumetric patterning, leveraging the Purcell effect [3, 4]. Each of these methods entail the development of dedicated nanofabrication methods to realize wavelength-scale patterns into scintillator materials. In this talk, I will review some recent theoretical and experimental developments in nanophotonic scintillators. I will first present a general theoretical framework to model scintillation in arbitrary nanophotonic structures, which also lends itself to shape optimization of nanophotonic structures for enhanced scintillation. Then, I will review some recent experimental demonstrations in surface-patterned photonic crystal scintillators and multilayer scintillators. Based on this framework and recent theoretical proposals, I will also present other nanophotonic scintillator designs for enhanced spatial resolution and efficiency, as well as software-hardware co-design of nanophotonic scintillators for enhanced x-ray imaging [5, 6].","lang":"eng"}],"citation":{"short":"C.

However, the intrinsic weakness of optical nonlinearity has largely limited the efficiency of nonlinear frequency conversion. Here, motivated by recent advances in using non-Hermitian photonics to enable non-reciprocal light transport, we explore how the interplay between non-Hermiticity and optical nonlinearity leads to a fundamentally new regime of nonlinear frequency conversion. We describe how nonreciprocity in coupling between discrete frequency modes can be engineered to yield unidirectional energy flow towards the boundary mode of a frequency comb, closely resembling a non-Hermitian skin effect. Applying this mechanism to an infrared (IR) comb with cascaded second-order nonlinearity, we demonstrate high (>85%) nonlinear conversion efficiency into the “skin” mode and high-power THz generation through enhancement of THz-creating nonlinear processes. We also show how these effects are robust to defects and disorder in the comb and can be harnessed to generate stable limit cycles and comb generation at IR and THz frequencies.","lang":"eng"}],"fulldoi":"https://doi.org/10.1117/12.3040830","volume":13347,"date_created":"2026-03-30T12:22:48Z","article_processing_charge":"No","type":"conference","title":"Non-reciprocal frequency conversion in a multimode nonlinear cavity","publication_identifier":{"issnl":["0277-786X"],"eisbn":["9781510684423"]},"arxiv":1,"date_published":"2025-03-21T00:00:00Z","external_id":{"arxiv":["2409.14299"]},"publication":"Nonlinear Frequency Generation and Conversion: Materials and Devices XXIV","scopus_import":"1","author":[{"full_name":"Pontula, Sahil","first_name":"Sahil","last_name":"Pontula"},{"last_name":"Vaidya","first_name":"Sachin","full_name":"Vaidya, Sachin"},{"id":"e2e68fc9-6505-11ef-a541-eb4e72cc3e82","full_name":"Roques-Carmes, Charles","first_name":"Charles","last_name":"Roques-Carmes"},{"first_name":"Shiekh Z.","last_name":"Uddin","full_name":"Uddin, Shiekh Z."},{"full_name":"Soljacic, Marin","last_name":"Soljacic","first_name":"Marin"},{"first_name":"Yannick","full_name":"Salamin, Yannick","last_name":"Salamin"}],"oa_version":"Preprint","main_file_link":[{"url":"https://doi.org/10.48550/arXiv.2409.14299","open_access":"1"}],"conference":{"start_date":"2025-01-25","end_date":"2025-01-31","name":"LASE","location":"San Francisco, CA, United States"},"_id":"21577"}]
