Noise mitigation in quantum enhanced fiber optic gyroscopes
Stefan Evans, Joanna Ptasinski·Sep 29, 2025
We analyze noise in a quantum-enhanced fiber optic gyroscope (FOG), focusing on one of the leading sources of phase uncertainty - uncorrelated photon saturation. Taking a squeezed state input as a source for N00N states, we compute the uncorrelated f...
Momentum-resolved two-dimensional spectroscopy as a probe of nonlinear quantum field dynamics
Duilio De Santis, Alex Gómez Salvador, Nataliia Bazhan +6 more·Sep 29, 2025
Emergent collective excitations constitute a hallmark of interacting quantum many-body systems, yet in solid-state platforms their study has been largely limited by the constraints of linear-response probes and by finite momentum resolution. We propo...
Quantitative quantum soundness for all multipartite compiled nonlocal games
Matilde Baroni, Igor Klep, Dominik Leichtle +4 more·Sep 29, 2025
Compiled nonlocal games transfer the power of Bell-type multi-prover tests into a single-device setting by replacing spatial separation with cryptography. Concretely, the KLVY compiler (STOC'23) maps any multi-prover game to an interactive single-pro...
Enhancing work-extraction in quantum batteries via correlated reservoirs
Sejal Ahuja, Tanoy Kanti Konar, Aditi Sen De·Sep 29, 2025
Going beyond isolated system dynamics, we examine how local and spatially correlated reservoirs influence the work extraction in quantum batteries. By employing a one-dimensional spin-1/2 model coupled to baths via dephasing and amplitude-damping noi...
Distributed Quantum Error Correction with Permutation-Invariant Approximate Codes
Connor Clayton, Bruno Avritzer·Sep 29, 2025
Modular quantum computing architectures require error correction schemes that remain effective in the presense of noisy inter-processor operations. We introduce a distributed quantum error correction framework based on approximate codes to address th...
Finite-Size Security Bounds in Semi-Quantum Key Distribution: Spectral, Operator-Theoretic, and Entropic Perspectives
Zahidur Rezwan Ratul·Sep 29, 2025
We study Semi-Quantum Key Distribution (SQKD) with a focus on finite-size security bounds, developed through three complementary perspectives. (i) Spectral disturbance: wrong-basis Lüders updates produce closed-form spectra and purity loss, which ser...
Unified laboratory-frame analysis of atomic gravitational-wave sensors
Simon Schaffrath, Daniel Störk, Fabio Di Pumpo +1 more·Sep 29, 2025
Atomic sensors using light-matter interactions, in particular atomic clocks and atom interferometers, have the potential to complement optical gravitational-wave detectors in the mid-frequency regime. Although both rely on interference, the interferi...
Agentic Exploration of Physics Models
Maximilian Nägele, Florian Marquardt·Sep 29, 2025
The process of scientific discovery relies on an interplay of observations, analysis, and hypothesis generation. Machine learning is increasingly being adopted to address individual aspects of this process. However, it remains an open challenge to fu...
Cryogenic pressure sensing with an ultrafast Meissner-levitated microrotor
Joel K Jose, Andrea Marchese, Marion Cromb +5 more·Sep 29, 2025
Magnetically levitated spinning rotors are key elements in important technologies such as navigation by gyroscopes, energy storage by flywheels, ultra-high vacuum generation by turbomolecular pumps, and pressure sensing for process control. However, ...
Quantum Dynamics with Time-Dependent Neural Quantum States
Alejandro Romero-Ros, Javier Rozalén Sarmiento, Arnau Rios·Sep 29, 2025
We present proof-of-principle time-dependent neural quantum state (NQS) simulations to illustrate the ability of this approach to effectively capture key aspects of quantum dynamics in the continuum. NQS leverage the parameterization of the wave func...
Near-Optimal Simultaneous Estimation of Quantum State Moments
Xiao Shi, Jiyu Jiang, Xian Wu +3 more·Sep 29, 2025
Estimating nonlinear properties such as Rényi entropies and observable-weighted moments serves as a central strategy for spectrum spectroscopy, which is fundamental to property prediction and analysis in quantum information science, statistical mecha...
The Quantum Decoding Problem : Tight Achievability Bounds and Application to Regev's Reduction
Agathe Blanvillain, André Chailloux, Jean-Pierre Tillich·Sep 29, 2025
We consider the quantum decoding problem. It consists in recovering a codeword given a superposition of noisy versions of this codeword. By measuring the superposition, we get back to the classical decoding problem. It appears for the first time in C...
Demonstration of quantum error detection in a silicon quantum processor
Chunhui Zhang, Chunhui Li, Zhen Tian +22 more·Sep 29, 2025
Quantum error detection is essential in realizing large-scale universal quantum computation, especially for quantum error correction (QEC). However, key elements for FTQC have yet to be realized in silicon qubits. Here, we demonstrate quantum error d...
Accelerating Regression Tasks with Quantum Algorithms
Chenghua Liu, Zhengfeng Ji·Sep 29, 2025
Regression is a cornerstone of statistics and machine learning, with applications spanning science, engineering, and economics. While quantum algorithms for regression have attracted considerable attention, most existing work has focused on linear re...

Cheng-Yun Ding, Wan-Fang Liu, Li-Hua Zhang +2 more·Sep 29, 2025
Due to its fast and robust characteristics, nonadiabatic geometric quantum computation with various optimized techniques has received much attention. However, these strategies either require precise pulse control or can only mitigate partial systemat...
An operator-based bound on information and disturbance in quantum measurements
Hollis Williams, Holger F. Hofmann·Sep 29, 2025
Quantum measurements can be described by operators that assign conditional probabilities to different outcomes while also describing unavoidable physical changes to the system. Here, we point out that operators describing information gain at minimal ...
An asymptotic field approach for the control of dipole emission in integrated structures
Vincenzo Macrì, Alice Viola, Marco Liscidini·Sep 29, 2025
We present a general framework to model spontaneous emission in integrated photonic structures by exploiting quantization of the electromagnetic field in terms of asymptotic in/out modes. This approach allows for an efficient and physically meaningfu...
