Entropy Flow and Exceptional-Point Structure in Two-Mode Squeezed-Bath Dynamics
Eric R. Bittner·Nov 24, 2025
Squeezed reservoirs provide a powerful means of engineering nonclassical noise and controlling irreversible dynamics in open quantum systems. Here we develop a comprehensive analysis of two coupled harmonic oscillators driven by independent squeezed ...
High-order splitting of non-unitary operators on quantum computers
Peter Brearley, Philipp Pfeffer·Nov 24, 2025
Dissipation and irreversibility are central to most physical processes, yet they lead to non-unitary dynamics that are challenging to realise on quantum processors. High-order operator splitting is an attractive approach for simulating unitary dynami...
Shake before use: universal enhancement of quantum thermometry by unitary driving
Emanuele Tumbiolo, Lorenzo Maccone, Chiara Macchiavello +2 more·Nov 24, 2025
Quantum thermometry aims at determining temperature with ultimate precision in the quantum regime. Standard equilibrium approaches, limited by the Quantum Fisher Information given by static energy fluctuations, lose sensitivity outside a fixed temper...
No-go theorems for sequential preparation of two-dimensional chiral states via channel-state correspondence
Ruihua Fan, Yantao Wu, Yimu Bao +1 more·Nov 24, 2025
We investigate whether sequential unitary circuits can prepare two-dimensional chiral states, using a correspondence between sequentially prepared states, isometric tensor network states, and one-dimensional quantum channel circuits. We establish two...
Quantum Hardware-Efficient Selection of Auxiliary Variables for QUBO Formulations
Damian Rovara, Lukas Burgholzer, Robert Wille·Nov 24, 2025
The Quantum Approximate Optimization Algorithm (QAOA) requires considered optimization problems to be translated into a compatible format. A popular transformation step in this pipeline involves the quadratization of higher-order binary optimization ...
Berry's phase on photonic quantum computers
Steven Abel, Iwo Wasek, Simon Williams·Nov 24, 2025
We formulate a continuous-variable quantum computing (CVQC) algorithm to study Berry's phase on photonic quantum computers. We demonstrate that CVQC allows the simulation of charged particles with orbital angular momentum under the influence of an ad...
Holographic duality between bulk topological order and boundary mixed-state order
Tsung-Cheng Lu, Yu-Jie Liu, Sarang Gopalakrishnan +1 more·Nov 24, 2025
We introduce a holographic framework for analyzing the steady states of repeated quantum channels with strong symmetries. Using channel-state duality, we show that the steady state of a $d$-dimensional quantum channel is holographically mapped to the...
Monogamy of Mutual Information in Graph States
Jesus Fuentes, Cynthia Keeler, William Munizzi +1 more·Nov 24, 2025
The monogamy of mutual information (MMI) is a quantum entropy inequality that enforces the non-positivity of tripartite information. We investigate the failure of MMI in graph states as a forbidden-subgraph phenomenon, conjecturing that every MMI-vio...
Topological BF Theory construction of twisted dihedral quantum double phases from spontaneous symmetry breaking
Zhi-Qiang Gao, Chunxiao Liu, Joel E. Moore·Nov 24, 2025
Nonabelian topological orders host exotic anyons central to quantum computing, yet established realizations rely on case-by-case constructions that are often conceptually involved. In this work, we present a systematic construction of nonabelian dihe...
Robotic chip-scale nanofabrication for superior consistency
Felix M. Mayor, Wenyan Guan, Erik Szakiel +2 more·Nov 24, 2025
Unlike the rigid, high-volume automation found in industry, academic research requires process flexibility that has historically relied on variable manual operations. This hinders the fabrication of advanced, complex devices. We propose to address th...
Modelling and experimental verification of photoelectrical response of NV diamond spin centres
Josef Soucek, Michael Petrov, Michal Gulka +2 more·Nov 24, 2025
We report on a mathematical model of the photoelectric response of NV colour centres in diamond, that can be employed for sensing and quantum science information applications. Although the model applies to NV centre in diamond, it can be applied with...
Entanglement-limited linear response in fermionic systems
Hadi Cheraghi, Ali G. Moghaddam, Teemu Ojanen·Nov 24, 2025
We propose a general connection between entanglement-entropy scaling laws and the linear response functions of particle-conserving fermionic systems in their ground state. Specifically, we show that the response to perturbations coupled to the partic...
Wigner and Gabor phase-space analysis of propagators for evolution equations
Elena Cordero, Gianluca Giacchi, Luigi Rodino·Nov 24, 2025
We study the Wigner kernel and the Gabor matrix associated with the propagators of a broad class of linear evolution equations, including the complex heat, wave, and Hermite equations. Within the framework of time-frequency analysis, we derive explic...
Neural surrogates for designing gravitational wave detectors
Carlos Ruiz-Gonzalez, Sören Arlt, Sebastian Lehner +5 more·Nov 24, 2025
Physics simulators are essential in science and engineering, enabling the analysis, control, and design of complex systems. In experimental sciences, they are increasingly used to automate experimental design, often via combinatorial search and optim...
Simulating dynamics of the two-dimensional transverse-field Ising model: a comparative study of large-scale classical numerics
Joseph Vovrosh, Sergi Julià-Farré, Wladislaw Krinitsin +11 more·Nov 24, 2025
The quantum dynamics of many-qubit systems is an outstanding problem that has recently driven significant advances in both numerical methods and programmable quantum processing units. In this work, we employ a comprehensive toolbox of state-of-the-ar...
Quantitative and Optimal Device-Independent Lower Bounds on Detection Efficiency
Arkaprabha Ghosal, Soumyadip Patra, Peter Bierhorst·Nov 24, 2025
This paper examines a quantitative and optimal lower bound on the detector efficiency in a (2,2,2) Bell experiment within a fully device-independent framework, whereby the detectors used in the experiment are uncharacterized. We provide a tight lower...

TorchQuantumDistributed (tqd) is a PyTorch-based [Paszke et al., 2019] library for accelerator-agnostic differentiable quantum state vector simulation at scale. This enables studying the behavior of learnable parameterized near-term and fault- tolera...
Performance Guarantees for Quantum Neural Estimation of Entropies
Sreejith Sreekumar, Ziv Goldfeld, Mark M. Wilde·Nov 24, 2025
Estimating quantum entropies and divergences is an important problem in quantum physics, information theory, and machine learning. Quantum neural estimators (QNEs), which utilize a hybrid classical-quantum architecture, have recently emerged as an ap...
Decoupling local classicality from classical explainability: A noncontextual model for bilocal classical theory and a locally-classical but contextual theory
Sina Soltani, Marco Erba, David Schmid +1 more·Nov 24, 2025
We construct an ontological model for the theory known as bilocal classical theory doi.org/10.1103/PhysRevA.102.052216. To our knowledge, this is only the second time that an ontological model has been constructed for an entire theory, rather than ju...
