Ergotropic Mpemba crossings in finite-dimensional quantum batteries
Triyas Sapui, Tanoy Kanti Konar, Aditi Sen De·Feb 11, 2026
The quantum Mpemba effect is a counterintuitive phenomenon in which a state initially farther from equilibrium relaxes more rapidly than one that starts nearer to equilibrium. In the context of finite-dimensional quantum batteries interacting with an...
Characterizing Trainability of Instantaneous Quantum Polynomial Circuit Born Machines
Kevin Shen, Susanne Pielawa, Vedran Dunjko +1 more·Feb 11, 2026
Instantaneous quantum polynomial quantum circuit Born machines (IQP-QCBMs) have been proposed as quantum generative models with a classically tractable training objective based on the maximum mean discrepancy (MMD) and a potential quantum advantage m...
Recirculating Quantum Photonic Networks for Fast Deterministic Quantum Information Processing
Emil Grovn, Matias Bundgaard-Nielsen, Jesper Mørk +2 more·Feb 11, 2026
A fundamental challenge in photonics-based deterministic quantum information processing is to realize key transformations on time scales shorter than those of detrimental decoherence and loss mechanisms. This challenge has been addressed through devi...
A generalization of Frenkel's formula
Shmuel Friedland·Feb 11, 2026
We generalize Frenkel's integral formula for traces of operators to operators. The resulting formula holds for bounded self-adjoint positive operators and $p$-Schatten class of compact positive operators.
Improving Quantum Multi-Objective Optimization with Archiving and Substitution
Linus Ekstrøm, Takafumi Hosogi, Xavier Bonet-Monroig +3 more·Feb 11, 2026
Finding optimal solutions of conflicting objectives is a daily matter in many industrial applications, with multi-objective optimization trying to find the best solutions to them. The advent of quantum computing has led to researchers wondering if th...
Quantum Optimization in Loc(Q)ation Science: QUBO Formulations, Benchmark Problems, and a Computational Study
Felix P. Broesamle, Stefan Nickel·Feb 11, 2026
Recent advances in quantum computing and the increasing availability of quantum hardware have substantially enhanced the practical relevance of quantum approaches to discrete optimization. Among these, the Quadratic Unconstrained Binary Optimization ...
Photon counting beyond the rotating-wave approximation
Steven Kim, Fabian Hassler·Feb 11, 2026
Open quantum systems are often described by a Lindblad master equation, which relies on a set of approximations, most importantly the rotating-wave approximation which is only valid for weak damping. In the Lindblad setting, dissipative processes are...
Reaching the quantum noise limit for interferometric measurement of optical nonlinearity in vacuum
Ali Aras, Adrien E. Kraych, Xavier Sarazin +3 more·Feb 11, 2026
Quantum Electrodynamics predicts that the vacuum must behave as a nonlinear optical medium:the vacuum optical index should increase when vacuum is stressed by intense electromagnetic fields.The DeLLight (Deflection of Light by Light) project aims to ...
Sub-Poissonian Statistics and Quantum Non-Gaussianity from High-Harmonic Generation
David Theidel, Mackrine Nahra, Ilya Karuseichyk +3 more·Feb 11, 2026
Quantum technologies are powered by platforms to generate complex non-classical states of matter or light to realize applications. We investigate the non-classical properties of high-harmonic generation in semiconductors, an emerging photonic platfor...
Multi-spin control from one-spin pulses
Suzanne Lim, Bowen Guo, Abi Turner +3 more·Feb 11, 2026
Controlling ensembles of weakly coupled spins typically requires computationally expensive multispin optimisations. We present a compact framework that enables control of weakly coupled spin systems (of any spin), but using RF pulses optimised for a ...
Mixed-State Topology in Non-Hermitian Systems
Shou-Bang Yang, Pei-Rong Han, Wen Ning +3 more·Feb 11, 2026
Non-Hermitian (NH) systems, owing to the existence of exceptional point (or ring and surface), exhibit exotic topological features which are inaccessible in Hermitian systems. While current studies on NH topology has primarily focused on pure states ...
Emulation of large-scale qubit registers with a phase space approach
Christian de Correc, Denis Lacroix, Corentin Bertrand·Feb 11, 2026
A phase-space approach is used and benchmarked for the simulation of the continuous-time evolution of large registers of qubits. It is based on a statistical ensemble of independent mean-field trajectories, where mean-field is introduced at the level...
Scaling and Universality at Noise-Affected Non-Equilibrium Spin Correlation Functions
R. Jafari, Alireza Akbari·Feb 11, 2026
We investigate scaling and universality in nonequilibrium spin correlation functions in the presence of uncorrelated noise. In the absence of noise, spin correlation functions exhibit a crossover from monotonic decay at fast sweep velocities to oscil...
Fault Tolerant Design of IGZO-based Binary Search ADCs
Paula Carolina Lozano Duarte, Sule Ozev, Mehdi Tahoori·Feb 11, 2026
Thin-film technologies such as Indium Gallium Zinc Oxide (IGZO) enable Flexible Electronics (FE) for emerging applications in wearable sensing, personal health monitoring, and large-area systems. Analog-to-digital converters (ADCs) serve as critical ...
Efficient Operator Selection and Warm-Start Strategy for Excitations in Variational Quantum Eigensolvers
Max Haas, Thierry N. Kaldenbach, Thomas Hammerschmidt +1 more·Feb 11, 2026
We present a novel approach for efficient preparation of electronic ground states, leveraging the optimizer ExcitationSolve [Jäger et al., Comm. Phys. (2025)] and established variational quantum eigensolver-based operator selection methods, such as E...
Between equilibrium and fluctuation: Einstein's heuristic argument and Boltzmann's principle
Enric Pérez, Antonio Gil·Feb 11, 2026
We critically revisit Einstein's 1905 heuristic argument for lightquanta, considering its internal coherence and the scope of its applicability. We argue that Einstein's reasoning, often celebrated for its originality, is ambiguous because it can be ...
A QFT information protocol for charged black holes
Paolo Palumbo·Feb 11, 2026
A generalization for the quantum information retrieval protocol recently illustrated by Verlinde and van der Heijden for evaporating black holes is provided to inclusions of type III von Neumann factors. The physical interest of such scenario arises ...
Error-Tolerant Quantum State Discrimination: Optimization and Quantum Circuit Synthesis
Chien-Kai Ma, Bo-Hung Chen, Tian-Fu Chen +2 more·Feb 11, 2026
We develop error-tolerant quantum state discrimination(QSD) strategies that maintain reliable performance under moderate noise. Two complementary approaches are proposed: CrossQSD, which generalizes unambiguous discrimination with tunable confidence ...
Experimental demonstration that qubits can be cloned at will, if encrypted with a single-use decryption key
Koji Yamaguchi, Leon Rullkötter, Ibrahim Shehzad +3 more·Feb 11, 2026
The no-cloning theorem forbids the creation of identical copies of qubits, thereby imposing strong limitations on quantum technologies. A recently-proposed protocol, encrypted cloning, showed, however, that the creation of perfect clones is theoretic...
Magneto-optical properties of the neutral silicon-vacancy center in diamond under extreme isotropic strain fields
Meysam Mohseni, Gergő Thiering, Adam Gali·Feb 11, 2026
The neutral silicon--vacancy (SiV$^{0}$) center in diamond combines inversion symmetry with optical emission, making it a robust quantum emitter resilient to stray electric fields. Using first-principles density-functional theory, we quantify its res...
