Non-Commutation Chains in Pre- and Post-Selection Paradoxes

Ouissal Moumou·Sep 18, 2025

Peculiar measurements can be obtained on systems that undergo both pre- and post-selection. We prove a conjecture from [1] on logical Pre- and Post-Selection (PPS) paradoxes for a restricted case. We prove that all of these paradoxes admit non-commut...

Bell Meets General Philosophers of Science : Reassessing Measurement Independence

Yuichiro Kitajima·Sep 17, 2025

Bell's inequality is derived from three assumptions: measurement independence, outcome independence, and parameter independence. Among these, measurement independence, often taken for granted, holds that hidden variables are statistically uncorrelate...

Quasi-Monte Carlo Method for Linear Combination Unitaries via Classical Post-Processing

Yuya Kawamata, Kosuke Mitarai, Keisuke Fujii·Sep 17, 2025

We propose the quasi-Monte Carlo method for linear combination of unitaries via classical post-processing (LCU-CPP) on quantum applications. The LCU-CPP framework has been proposed as an approach to reduce hardware resources, expressing a general tar...

On the Complexity of Decoded Quantum Interferometry

Kunal Marwaha, Bill Fefferman, Alexandru Gheorghiu +1 more·Sep 17, 2025

We study the complexity of Decoded Quantum Interferometry (DQI), a quantum algorithm for approximate optimization. First, we show that the algorithm resists classical simulation strategies based on locating outputs with large probabilities. We then p...

Warm-Starting PCE for Traveling Salesman Problem

Rafael S. do Carmo, Renato Gomes dos Reis, Samuel Fernando F Silva +2 more·Sep 17, 2025

Variational quantum algorithms are promising for combinatorial optimization, but their scalability is often limited by qubit-intensive encoding schemes. To overcome this bottleneck, Pauli Correlation Encoding (PCE) has emerged as one of the most prom...

Quenched properties of the Spectral Form Factor

Dimitrios Charamis, Manas Kulkarni, Jorge Kurchan +1 more·Sep 17, 2025

The Spectral Form Factor (SFF) is defined as the modulus squared of the partition function in complex temperature for hermitian matrices and a suitable generalisation has been given in the non hermitian case. In this work we compute the properties of...

Quantum-like representation of neuronal networks' activity: modeling "mental entanglement"

Andrei Khrennikov, Makiko Yamada·Sep 17, 2025

Quantum-like modeling (QLM) - quantum theory applications outside of physics - are intensively developed with applications in biology, cognition, psychology, and decision-making. For cognition, QLM should be distinguished from quantum reductionist mo...

Comparing Quantum Annealing and BF-DCQO

Pau Farré, Erika Ordog, Kevin Chern +1 more·Sep 17, 2025

Recent work [1] has claimed that a gate-model quantum-classical hybrid algorithm called bias-field digitized counterdiabatic quantum optimization (BF-DCQO) [2] outperforms D-Wave's annealing quantum computers in optimization tasks. We find the opposi...

Electron distributions of molecular domains: canonical ensemble, and charge transfer electronegativity relationship

Roberto Carlos Bochicchio·Sep 17, 2025

The principle of maximum entropy (MaxEnt) applies to the canonical ensemble related to the number of particles, known as the $\mathcal{N}$-ensemble. This concept pertains to physical domains (or basins) that are treated as open systems capable of tra...
