Generation of 12 dB squeezed light from a waveguide optical parametric amplifier using a machine-learning-controlled spatial light modulator
Gyeongmin Ha, Kazuki Hirota, Takahiro Kashiwazaki +5 more·Mar 3, 2026
We demonstrate the generation of $12.1 \pm 0.2$ dB squeezed light from a periodically poled lithium niobate (PPLN) waveguide optical parametric amplifier (OPA). While single-pass OPAs offer squeezed light with THz-order bandwidths, loss from spatial ...
Geometric mechanisms enabling spin- and enantio-sensitive observables in one photon ionization of chiral molecules
Philip Caesar M. Flores, Stefanos Carlström, Serguei Patchkovskii +3 more·Mar 3, 2026
We examine spin-resolved photoionization of randomly oriented chiral molecules via circularly polarized light, and revisit earlier predictions of Cherepkov (J. Phys. B: Atom. Mol. Phys. 16, 1543, 1983). We will show that the dynamical origin of spin-...
Non-commutative integration method and generalized coherent states
A. I. Breev, D. M. Gitman·Mar 3, 2026
The relationship between states obtained by the non-commutative integration method of the Schrödinger equation on Lie groups and generalized coherent states is investigated. It is shown that such solutions belong to the class of generalized coherent ...
Correction scheme for total energy obtained on fault-tolerant quantum computer via quantum dominant orbital selection and subspace dynamical correlation methods
Nobuki Inoue, Hisao Nakamura·Mar 3, 2026
We propose a practical method for accurately evaluating molecular energies using a hybrid approach that integrates fault-tolerant quantum computers with classical computing. Our scheme comprises two complementary methods: quantum dominant orbital sel...
Neural quantum support vector data description for one-class classification
Changjae Im, Hyeondo Oh, Daniel K. Park·Mar 3, 2026
One-class classification (OCC) is a fundamental problem in machine learning with numerous applications, such as anomaly detection and quality control. With the increasing complexity and dimensionality of modern datasets, there is a growing demand for...
Causal Learning Should Embrace the Wisdom of the Crowd
Ryan Feng Lin, Yuantao Wei, Huiling Liao +2 more·Mar 3, 2026
Learning causal structures typically represented by directed acyclic graphs (DAGs) from observational data is notoriously challenging due to the combinatorial explosion of possible graphs and inherent ambiguities in observations. This paper argues th...
Qudit Designs and Where to Find Them
Namit Anand, Jeffrey Marshall, Jason Saied +2 more·Mar 3, 2026
Unitary t-designs are some of the most versatile tools in quantum information theory. Their applications range from randomized benchmarking and shadow tomography, to more fundamental ones such as emulating quantum chaos and establishing exponential s...
Quantum Algorithms for Approximate Graph Isomorphism Testing
Prateek P. Kulkarni·Mar 3, 2026
The graph isomorphism problem asks whether two graphs are identical up to vertex relabeling. While the exact problem admits quasi-polynomial-time classical algorithms, many applications in molecular comparison, noisy network analysis, and pattern rec...
Rate-Fidelity Tradeoffs in All-Photonic and Memory-Equipped Quantum Switches
Panagiotis Promponas, Leonardo Bacciottini, Paul Polakos +3 more·Mar 3, 2026
Quantum entanglement switches are a key building block for early quantum networks, and a central design question is whether near-term devices should use only flying photons or also incorporate quantum memories. We compare two architectures: an all-ph...
Ultra-low loss piezo-optomechanical low-confinement silicon nitride platform for visible wavelength quantum photonic circuits
Mayank Mishra, Gwangho Choi, Wenhua He +7 more·Mar 3, 2026
The stringent demands of photonic quantum computing protocols motivate photonic integrated circuit (PIC) platforms with passive optical properties such as extremely low losses and correspondingly large circuit depths, as well as active optical proper...

Anirudh Lanka, Juan Garcia-Nila, Todd A. Brun·Mar 3, 2026
Continuous measurement-based holonomic quantum computation provides a route to universal logical computation in quantum error correcting codes. We introduce a fault-tolerant framework for implementing measurement-based holonomic gates that leverages ...

Human-Certified Module Repositories (HCMRs) are introduced in this work as a new architectural model for constructing trustworthy software in the era of AI-assisted development. As large language models increasingly participate in code generation, co...
Measurement of a quantum system using spin-mechanical conversion
A. A. Wood, D. S. Rice, T. Xie +5 more·Mar 3, 2026
Levitated macroscopic particles exhibiting quantum mechanical effects are garnering increased attention as a means for precision sensing and testing quantum mechanics. Defects in diamond, such as the nitrogen-vacancy (NV) centre possess optically-add...

Megha Khokhar, Lucas Norder, Paolo M. Sberna +1 more·Mar 3, 2026
High-stress silicon nitride (Si3N4) membranes represent the state-of-the-art for cavity optomechanics, combining ultralow dissipation, optical transparency, and full compatibility with wafer-scale nanofabrication. Yet their integration into high-fine...
RIS-Enabled Wireless Channel Equalization: Adaptive RIS Equalizer and Deep Reinforcement Learning
Gal Ben-Itzhak, Ender Ayanoglu·Mar 3, 2026
Reconfigurable Intelligent Surfaces (RISs) offer a promising means of reshaping the wireless propagation environment, yet practical methods for configuring large passive arrays to achieve reliable signal equalization remain limited. Equalization is e...

We propose a method for solving the Jalilian-Marian-Iancu-McLerran-Weigert-Leonidov-Kovner (JIMWLK) evolution equation on quantum computers. Our approach exploits the reformulation of the JIMWLK equation as a Lindblad master equation governing the ra...
VA-DAR: A PQC-Ready, Vendor-Agnostic Deterministic Artifact Resolution for Serverless, Enumeration-Resistant Wallet Recovery
Jian Wang·Mar 3, 2026
Serverless wallet recovery must balance portability, usability, and privacy. Public registries enable decentralized lookup but naive identifier hashing leaks membership through enumeration. We present VA-DAR, a keyed-discovery protocol for ACE-GF-bas...
