Probabilistic Links Between Quantum Classification of Patterns of Boolean Functions and Hamming Distance

Theodore Andronikos, Constantinos Bitsakos, Konstantinos Nikas +2 more·Oct 14, 2025

This article investigates the probabilistic relationship between quantum classification of Boolean functions and their Hamming distance. By integrating concepts from quantum computing, information theory, and combinatorics, we explore how Hamming dis...

Temperature and conditions for thermalization after canonical quenches

Lennart Dabelow·Oct 14, 2025

We consider quenches of a quantum system that is prepared in a canonical equilibrium state of one Hamiltonian and then evolves unitarily in time under a different Hamiltonian. Technically, our main result is a systematic expansion of the pre- and pos...

Multi-Copy Security in Unclonable Cryptography

Alper Çakan, Vipul Goyal, Fuyuki Kitagawa +2 more·Oct 14, 2025

Unclonable cryptography leverages the quantum no-cloning principle to copy-protect cryptographic functionalities. While most existing works address the basic single-copy security, the stronger notion of multi-copy security remains largely unexplored....

Quantum thermodynamics of Gross-Pitaevskii qubits

Sebastian Deffner·Oct 14, 2025

What are the resources that can be leveraged for a thermodynamic device to exhibit genuine quantum advantage? Typically, the answer to this question is sought in quantum correlations. In the present work, we show that quantum Otto engines that operat...

Bayes or Heisenberg: Who(se) Rules?

Volker Tresp, Hang Li, Federico Harjes +1 more·Oct 14, 2025

Although quantum systems are generally described by quantum state vectors, we show that in certain cases their measurement processes can be reformulated as probabilistic equations expressed in terms of probabilistic state vectors. These probabilistic...

A universal approach to saddle-point methods in attosecond science

Anne Weber, Job Feldbrugge, Emilio Pisanty·Oct 14, 2025

Light-matter interactions within the strong-field regime, where intense laser fields can ionise a target via tunnelling, give rise to fascinating phenomena such as the generation of high-order harmonic radiation (HHG). On the atomic scale, these stro...

Semiclassical analytical solutions of the eigenstate thermalization hypothesis in a quantum billiard

Yaoqi Ye, Chengkai Lin, Xiao Wang·Oct 14, 2025

We derive semiclassical analytical solutions for both the diagonal and off-diagonal functions in the eigenstate thermalization hypothesis (ETH) in a quarter-stadium quantum billiard. For a representative observable, we obtain an explicit expression a...

The logic of quantum mechanics

Eric Buffenoir·Oct 14, 2025

The quantum logic program originated in a 1936 article by G. Birkhoff and J. von Neumann. This program is generally disregarded due to no-go theorems restricting the existence of the tensor product of elementary quantum logics and, above all, the imp...

Experimental verification of multi-copy activation of genuine multipartite entanglement

Robert Stárek, Tim Gollerthan, Olga Leskovjanová +5 more·Oct 14, 2025

A central concept in quantum information processing is genuine multipartite entanglement (GME), a type of correlation beyond biseparability, that is, correlations that cannot be explained by statistical mixtures of partially separable states. GME is ...

Neural Guided Sampling for Quantum Circuit Optimization

Bodo Rosenhahn, Tobias J. Osborne, Christoph Hirche·Oct 14, 2025

Translating a general quantum circuit on a specific hardware topology with a reduced set of available gates, also known as transpilation, comes with a substantial increase in the length of the equivalent circuit. Due to decoherence, the quality of th...
