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."}],"date_updated":"2026-04-27T08:37:35Z","publication_identifier":{"eissn":["2041-1723"]},"volume":16,"language":[{"iso":"eng"}],"doi":"10.1038/s41467-025-63035-8","citation":{"short":"S.

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.","lang":"eng"}],"OA_place":"repository","ddc":["530"],"title":"Noise-immune quantum correlations of intense light","OA_type":"green","scopus_import":"1","type":"journal_article","date_published":"2025-05-14T00:00:00Z","publication":"Nature Photonics"},{"issue":"8044","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","extern":"1","month":"01","year":"2025","quality_controlled":"1","pmid":1,"article_type":"original","oa_version":"Preprint","page":"52-56","publication_status":"published","intvolume":" 637","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2406.00321"}],"external_id":{"pmid":["39743600"],"arxiv":["2406.00321"]},"arxiv":1,"author":[{"last_name":"Cheng","full_name":"Cheng, Dali","first_name":"Dali"},{"first_name":"Kai","full_name":"Wang, Kai","last_name":"Wang"},{"full_name":"Roques-Carmes, Charles","id":"e2e68fc9-6505-11ef-a541-eb4e72cc3e82","first_name":"Charles","last_name":"Roques-Carmes"},{"first_name":"Eran","full_name":"Lustig, Eran","last_name":"Lustig"},{"last_name":"Long","full_name":"Long, Olivia Y.","first_name":"Olivia Y."},{"first_name":"Heming","full_name":"Wang, Heming","last_name":"Wang"},{"full_name":"Fan, Shanhui","first_name":"Shanhui","last_name":"Fan"}],"OA_type":"green","title":"Non-Abelian lattice gauge fields in photonic synthetic frequency dimensions","OA_place":"repository","ddc":["530"],"publication":"Nature","date_published":"2025-01-02T00:00:00Z","type":"journal_article","scopus_import":"1","article_processing_charge":"No","status":"public","date_created":"2026-03-30T12:22:47Z","oa":1,"_id":"21548","day":"02","publisher":"Springer Nature","date_updated":"2026-04-27T07:14:06Z","abstract":[{"lang":"eng","text":"Non-Abelian gauge fields provide a conceptual framework to describe particles\r\nhaving spins, underlying many phenomena in electrodynamics, condensed-matter\r\nphysics and particle physics.

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."}],"_id":"21549","publisher":"Springer Nature","day":"09","oa":1,"date_created":"2026-03-30T12:22:47Z","article_processing_charge":"No","status":"public","pmid":1,"article_type":"original","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","image":"/images/cc_by_nc_nd.png","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","short":"CC BY-NC-ND (4.0)"},"quality_controlled":"1","year":"2025","extern":"1","month":"04","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","author":[{"full_name":"Hua, Shiyue","first_name":"Shiyue","last_name":"Hua"},{"first_name":"Erwan","full_name":"Divita, Erwan","last_name":"Divita"},{"last_name":"Yu","full_name":"Yu, Shanshan","first_name":"Shanshan"},{"last_name":"Peng","full_name":"Peng, Bo","first_name":"Bo"},{"last_name":"Roques-Carmes","full_name":"Roques-Carmes, Charles","id":"e2e68fc9-6505-11ef-a541-eb4e72cc3e82","first_name":"Charles"},{"first_name":"Zhan","full_name":"Su, Zhan","last_name":"Su"},{"last_name":"Chen","first_name":"Zhang","full_name":"Chen, Zhang"},{"full_name":"Bai, Yanfei","first_name":"Yanfei","last_name":"Bai"},{"last_name":"Zou","first_name":"Jinghui","full_name":"Zou, Jinghui"},{"last_name":"Zhu","first_name":"Yunpeng","full_name":"Zhu, Yunpeng"},{"full_name":"Xu, Yelong","first_name":"Yelong","last_name":"Xu"},{"full_name":"Lu, Cheng-kuan","first_name":"Cheng-kuan","last_name":"Lu"},{"last_name":"Di","full_name":"Di, Yuemiao","first_name":"Yuemiao"},{"full_name":"Chen, Hui","first_name":"Hui","last_name":"Chen"},{"first_name":"Lushan","full_name":"Jiang, Lushan","last_name":"Jiang"},{"full_name":"Wang, Lijie","first_name":"Lijie","last_name":"Wang"},{"last_name":"Ou","full_name":"Ou, Longwu","first_name":"Longwu"},{"last_name":"Zhang","full_name":"Zhang, Chaohong","first_name":"Chaohong"},{"last_name":"Chen","first_name":"Junjie","full_name":"Chen, Junjie"},{"first_name":"Wen","full_name":"Zhang, Wen","last_name":"Zhang"},{"last_name":"Zhu","first_name":"Hongyan","full_name":"Zhu, Hongyan"},{"last_name":"Kuang","full_name":"Kuang, Weijun","first_name":"Weijun"},{"last_name":"Wang","full_name":"Wang, Long","first_name":"Long"},{"first_name":"Huaiyu","full_name":"Meng, Huaiyu","last_name":"Meng"},{"full_name":"Steinman, Maurice","first_name":"Maurice","last_name":"Steinman"},{"last_name":"Shen","first_name":"Yichen","full_name":"Shen, Yichen"}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.1038/s41586-025-08786-6"}],"external_id":{"pmid":[" 40205213"]},"intvolume":" 640","publication_status":"published","page":"361-367","oa_version":"Published Version"},{"user_id":"ba8df636-2132-11f1-aed0-ed93e2281fdd","month":"02","extern":"1","year":"2025","quality_controlled":"1","tmp":{"image":"/images/cc_by.png","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"article_number":"31","article_type":"original","oa_version":"Published Version","publication_status":"published","intvolume":" 8","external_id":{"arxiv":["2406.04000"]},"main_file_link":[{"url":"https://doi.org/10.1038/s42005-025-01953-1","open_access":"1"}],"author":[{"first_name":"Michael","full_name":"Horodynski, Michael","last_name":"Horodynski"},{"last_name":"Roques-Carmes","id":"e2e68fc9-6505-11ef-a541-eb4e72cc3e82","first_name":"Charles","full_name":"Roques-Carmes, Charles"},{"full_name":"Salamin, Yannick","first_name":"Yannick","last_name":"Salamin"},{"full_name":"Choi, Seou","first_name":"Seou","last_name":"Choi"},{"last_name":"Sloan","first_name":"Jamison","full_name":"Sloan, Jamison"},{"last_name":"Luo","first_name":"Di","full_name":"Luo, Di"},{"full_name":"Soljačić, Marin","first_name":"Marin","last_name":"Soljačić"}],"arxiv":1,"OA_type":"gold","DOAJ_listed":"1","title":"Stochastic logic in biased coupled photonic probabilistic bits","ddc":["530"],"OA_place":"publisher","publication":"Communications Physics","date_published":"2025-02-20T00:00:00Z","type":"journal_article","scopus_import":"1","status":"public","article_processing_charge":"No","oa":1,"license":"https://creativecommons.org/licenses/by/4.0/","date_created":"2026-03-30T12:22:47Z","day":"20","publisher":"Springer Nature","_id":"21550","abstract":[{"lang":"eng","text":"Optical computing often employs tailor-made hardware to implement specific algorithms, trading generality for improved performance in key aspects like speed and power efficiency.

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."}],"date_updated":"2026-04-27T10:32:06Z","publication_identifier":{"issn":["2643-1564"]},"language":[{"iso":"eng"}],"volume":7,"doi":"10.1103/physrevresearch.7.l012014","citation":{"ista":"Karnieli A, Tziperman O, Roques-Carmes C, Fan S. 2025.

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."}],"citation":{"chicago":"Gu, Alex, Jamison Sloan, Charles Roques-Carmes, Seou Choi, Eric I.

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]."}],"date_updated":"2026-05-05T09:53:32Z","author":[{"first_name":"Charles","id":"e2e68fc9-6505-11ef-a541-eb4e72cc3e82","full_name":"Roques-Carmes, Charles","last_name":"Roques-Carmes"}],"doi":"10.1109/nss/mic/rtsd57106.2025.11287777","citation":{"ieee":"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."}],"publication_identifier":{"eisbn":["9781510684423"],"issnl":["0277-786X"]},"title":"Non-reciprocal frequency conversion in a multimode nonlinear cavity","OA_place":"repository","OA_type":"green","type":"conference","scopus_import":"1","publication":"Nonlinear Frequency Generation and Conversion: Materials and Devices XXIV","date_published":"2025-03-21T00:00:00Z"},{"year":"2025","quality_controlled":"1","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","month":"04","extern":"1","conference":{"end_date":"2025-01-31","name":"OPTO","start_date":"2025-01-25","location":"San Francisco, CA, United States"},"article_number":"1337702","publication_status":"published","oa_version":"Preprint","external_id":{"arxiv":["2409.17002"]},"main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2409.17002"}],"author":[{"last_name":"Long","first_name":"Olivia","full_name":"Long, Olivia"},{"full_name":"Pajovic, Simo","first_name":"Simo","last_name":"Pajovic"},{"last_name":"Roques-Carmes","id":"e2e68fc9-6505-11ef-a541-eb4e72cc3e82","first_name":"Charles","full_name":"Roques-Carmes, Charles"},{"last_name":"Tsurimaki","first_name":"Yoichiro","full_name":"Tsurimaki, Yoichiro"},{"last_name":"Rivera","first_name":"Nicholas","full_name":"Rivera, Nicholas"},{"full_name":"Soljacic, Marin","first_name":"Marin","last_name":"Soljacic"},{"first_name":"Svetlana","full_name":"Boriskina, Svetlana","last_name":"Boriskina"},{"last_name":"Fan","full_name":"Fan, Shanhui","first_name":"Shanhui"}],"arxiv":1,"intvolume":" 13377","title":"Nonreciprocal scintillation using magneto-optical photonic crystals","OA_place":"repository","OA_type":"green","type":"conference","scopus_import":"1","publication":"Photonic and Phononic Properties of Engineered Nanostructures XV","date_published":"2025-04-01T00:00:00Z","oa":1,"date_created":"2026-03-30T12:22:48Z","publisher":"SPIE","day":"01","_id":"21578","status":"public","article_processing_charge":"No","language":[{"iso":"eng"}],"volume":13377,"citation":{"ama":"Long O, Pajovic S, Roques-Carmes C, et al.

Scintillation can therefore be controlled and enhanced via nanophotonic effects, which has been experimentally demonstrated in recent works. Such designs have thus far obeyed Lorentz reciprocity, meaning there is a direct equivalence between scintillation emission from the design and absorption of a plane wave in the far-field. However, scintillators that do not obey reciprocity have not been explored, even though they represent a novel platform for probing emission which is both nonequilibrium and nonreciprocal in nature. In this work, we propose to harness nonreciprocity to achieve directional control of scintillation emission, granting an additional degree of control over scintillation. Such directionality of light output is important in improving collection efficiencies along off-normal directions towards detectors in certain radiation detection schemes. We present the design of a nonreciprocal scintillator using a one-dimensional magnetophotonic crystal in the Voigt configuration. Our work demonstrates the potential of controlling nonequilibrium emission such as scintillation by breaking reciprocity and expands the space of nanophotonic design for achieving such control."}],"date_updated":"2026-05-05T10:50:08Z","publication_identifier":{"issnl":["0277-786X"],"eisbn":["9781510685024"]}},{"OA_type":"closed access","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","extern":"1","month":"03","year":"2025","title":"Quantum tomography and intracavity dynamics with a biased optical parametric oscillator","quality_controlled":"1","conference":{"name":"OPTO","location":"San Francisco, CA, United States","start_date":"2025-01-25","end_date":"2025-01-31"},"publication":"AI and Optical Data Sciences VI","article_number":"133750E ","date_published":"2025-03-21T00:00:00Z","type":"conference","scopus_import":"1","article_processing_charge":"No","status":"public","oa_version":"None","date_created":"2026-03-30T12:22:48Z","_id":"21579","day":"21","publisher":"SPIE","publication_status":"published","date_updated":"2026-05-05T10:48:34Z","intvolume":" 13375","abstract":[{"lang":"eng","text":"We propose and experimentally demonstrate a method to study intracavity quantum states and their dynamics in an optical parametric oscillator (OPO). By measuring the OPO steady state’s sensitivity to an external bias field, we show how intracavity quantum states can be reconstructed. Our method includes precise control over the pump phase, facilitating arbitrary quadrature reconstruction and enabling complete visualization of cavity states using Husimi Q-function representations. We experimentally demonstrate the quantum tomography of an intracavity squeezed vacuum state generated by an OPO pumped below threshold. Additionally, by controlling the bias time delay and amplitude relative to the pump it allows for the reconstruction of the intracavity state at various times, offering insights into the temporal evolution of the OPO intracavity state. This approach provides a powerful tool for exploring and understanding the intricate behavior of quantum states within optical cavities."}],"publication_identifier":{"eisbn":["9781510685024"],"issnl":["0277-786X"]},"volume":13375,"language":[{"iso":"eng"}],"citation":{"ieee":"Y.
