These devices tackle the problem of decomposing and measuring multimode light fields, both partially coherent and quantum, without requiring prior knowledge of the modes involved. Classical strategies for modal decomposition—such as Karhunen-Loève expansions [1] for partially coherent beams or Schmidt decompositions [2] for bipartite quantum states—often rely on comprehensive tomography and complex data processing. By contrast, VOPs discover the relevant modes in situ through a simple optimization of detection signals at their outputs (e.g., measured optical power or coincidence counts), eliminating the overhead usually associated with scanning and reconstruction. Prior demonstrations of self-configuring photonic networks have proven the feasibility of such approaches for analyzing and generating multimode coherent optical fields [3]. article_processing_charge: No author: - first_name: Charles full_name: Roques-Carmes, Charles id: e2e68fc9-6505-11ef-a541-eb4e72cc3e82 last_name: Roques-Carmes - first_name: Aviv full_name: Karnieli, Aviv last_name: Karnieli - first_name: David A.B. full_name: Miller, David A.B. last_name: Miller - first_name: Shanhui full_name: Fan, Shanhui last_name: Fan citation: ama: 'Roques-Carmes C, Karnieli A, Miller DAB, Fan S.

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. article_number: '1334708 ' article_processing_charge: No arxiv: 1 author: - first_name: Sahil full_name: Pontula, Sahil last_name: Pontula - first_name: Sachin full_name: Vaidya, Sachin last_name: Vaidya - first_name: Charles full_name: Roques-Carmes, Charles id: e2e68fc9-6505-11ef-a541-eb4e72cc3e82 last_name: Roques-Carmes - first_name: Shiekh Z. full_name: Uddin, Shiekh Z. last_name: Uddin - first_name: Marin full_name: Soljacic, Marin last_name: Soljacic - first_name: Yannick full_name: Salamin, Yannick last_name: Salamin citation: ama: 'Pontula S, Vaidya S, Roques-Carmes C, Uddin SZ, Soljacic M, Salamin Y.

Here, we demonstrate that by applying vacuum-level coherent biasing, OPOs can be engineered as versatile hardware elements for stochastic computing. Specifically, we present a time-multiplexed, biased OPO system that enables discriminative and generative machine learning tasks, such as uncertainty-aware classification and the generation of MNIST digits directly from quantum vacuum noise. Beyond machine learning, we propose the use of biased OPO arrays for implementing fundamental stochastic logic gates and solving combinatorial optimization problems. Finally, we discuss the potential of on-chip OPO systems, which promise substantial improvements in latency and energy efficiency, paving the way for integrated stochastic computing architectures. article_number: '133750N ' article_processing_charge: No author: - first_name: Charles full_name: Roques-Carmes, Charles id: e2e68fc9-6505-11ef-a541-eb4e72cc3e82 last_name: Roques-Carmes - first_name: Yannick full_name: Salamin, Yannick last_name: Salamin - first_name: Seou full_name: Choi, Seou last_name: Choi - first_name: Michael full_name: Horodynski, Michael last_name: Horodynski - first_name: Jamison full_name: Sloan, Jamison last_name: Sloan - first_name: Di full_name: Luo, Di last_name: Luo - first_name: Marin full_name: Soljacic, Marin last_name: Soljacic citation: ama: 'Roques-Carmes C, Salamin Y, Choi S, et al.

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]. article_processing_charge: No author: - first_name: Charles full_name: Roques-Carmes, Charles id: e2e68fc9-6505-11ef-a541-eb4e72cc3e82 last_name: Roques-Carmes citation: ama: 'Roques-Carmes C.

This process operates on multiple timescales, with the final radiative step consisting of spontaneous emission, which can be modeled within the framework of fluctuational electrodynamics. 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. article_number: '1337702' article_processing_charge: No arxiv: 1 author: - first_name: Olivia full_name: Long, Olivia last_name: Long - first_name: Simo full_name: Pajovic, Simo last_name: Pajovic - first_name: Charles full_name: Roques-Carmes, Charles id: e2e68fc9-6505-11ef-a541-eb4e72cc3e82 last_name: Roques-Carmes - first_name: Yoichiro full_name: Tsurimaki, Yoichiro last_name: Tsurimaki - first_name: Nicholas full_name: Rivera, Nicholas last_name: Rivera - first_name: Marin full_name: Soljacic, Marin last_name: Soljacic - first_name: Svetlana full_name: Boriskina, Svetlana last_name: Boriskina - first_name: Shanhui full_name: Fan, Shanhui last_name: Fan citation: ama: 'Long O, Pajovic S, Roques-Carmes C, et al.

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.

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, limiting our ability to observe quantum states generated in optical cavities. Here, we propose a framework for observing the dynamics of quantum states generated inside nonlinear optical cavities. We utilize symmetry-breaking to obtain high sensitivity to small perturbations introduced to the quantum state, resulting in an asymmetric equilibrium of a macroscopic observable. With a nonlinear response at the single photon level, our approach directly imprints the field distribution of the cavity quantum state onto the statistics of bistable cavity steady-states. We experimentally demonstrate our approach in a degenerate optical parametric oscillator, generating and reconstructing the quasi-probability distribution of 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 such as soliton generation and Kerr frequency combs. article_processing_charge: No author: - first_name: Seou full_name: Choi, Seou last_name: Choi - first_name: Yannick full_name: Salamin, Yannick last_name: Salamin - first_name: Charles full_name: Roques-Carmes, Charles id: e2e68fc9-6505-11ef-a541-eb4e72cc3e82 last_name: Roques-Carmes - first_name: Jamison full_name: Sloan, Jamison last_name: Sloan - first_name: Michael full_name: Horodynski, Michael last_name: Horodynski - first_name: Marin full_name: Soljačić, Marin last_name: Soljačić citation: ama: Choi S, Salamin Y, Roques-Carmes C, Sloan J, Horodynski M, Soljačić M.

However, cloud networks can experience disruptions such as network partitions, high-loss links, and configuration errors. These disruptions interfere with the operation of leader-based protocols, as their view change mechanisms interrupt the normal case replication and cause the system to stall. We propose RACS, a novel randomized consensus protocol that ensures robustness against adversarial network conditions. RACS achieves optimal one-round trip latency under synchronous network conditions while remaining resilient to adversarial network conditions. RACS follows a simple design inspired by Raft, the most widely used consensus protocol in the cloud, and therefore enables seamless integration with the existing cloud software stack. Experiments with a prototype running on Amazon EC2 show that RACS achieves 28k cmd/sec throughput, ninefold higher than Raft under adversarial cloud network conditions. Under synchronous network conditions, RACS matches the performance of Multi-Paxos and Raft, achieving a throughput of 200k cmd/sec with a median latency of 300ms, confirming that RACS introduces no unnecessary overhead. Finally, SADL-RACS, a throughput-optimized version of RACS, achieves a throughput of 500k cmd/sec, delivering 150 percent higher throughput than Raft. article_processing_charge: No arxiv: 1 author: - first_name: Pasindu full_name: Tennage, Pasindu last_name: Tennage - first_name: Antoine full_name: Desjardins, Antoine id: 06d0c166-aec1-11ee-a7c0-b96e840a602b last_name: Desjardins - first_name: Eleftherios full_name: Kokoris Kogias, Eleftherios id: f5983044-d7ef-11ea-ac6d-fd1430a26d30 last_name: Kokoris Kogias orcid: 0000-0002-8827-3382 citation: ama: 'Tennage P, Desjardins A, Kokoris Kogias E.
