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...

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...
