Harnessing Environmental Memory with Reinforcement Learning in Open Quantum Systems

Safae Gaidi, Abdallah Slaoui, Mohammed EL Falaki +1 more·Jan 3, 2026

Non-Markovian memory effects in open quantum systems provide valuable resources for preserving coherence and enhancing controllability. However, exploiting them requires strategies adapted to history-dependent dynamics. We introduce a reinforcement-l...

How Alice, long before her time, derived the principles of quantum mechanics

Marcello Poletti·Jan 3, 2026

This philosophical dialogue explores the idea that the foundational principles of quantum mechanics need not be interpreted as describing a new physics, but may instead arise from the logical necessity of formalising the act of measurement within a c...

Constant Depth Digital-Analog Counterdiabatic Quantum Computing

Balaganchi A. Bhargava, Shubham Kumar, Anne-Maria Visuri +3 more·Jan 3, 2026

We introduce a digital-analog quantum computing framework that enables counterdiabatic protocols to be implemented at constant circuit depth, allowing fast and resource-efficient quantum state preparation on current quantum hardware. Counterdiabatic ...

Single-Shot and Few-Shot Decoding via Stabilizer Redundancy in Bivariate Bicycle Codes

Mohammad Rowshan·Jan 3, 2026

Bivariate bicycle (BB) codes are a prominent class of quantum LDPC codes constructed from group algebras. While the logical dimension and quantum distance of \emph{coprime} BB codes are known to be determined by a greatest common divisor polynomial $...

The Completeness of Eigenstates in Quantum Mechanics

Guoping Zhang·Jan 3, 2026

We delineate the scope of research on the completeness of eigenstates in quantum mechanics. Based on the limit of the potential function at infinity, the proof of completeness is divided into eight cases, and theoretical proofs or numerical simulatio...

Non-Markovian and Thermodynamic Signatures in the Classicality Assessment via Kolmogorov Consistency

Arghya Maity, Ahana Ghoshal, Kelvin Onggadinata +1 more·Jan 3, 2026

The Kolmogorov consistency condition (KCC) defines the statistical boundary between classical and quantum dynamics. Its violation signifies the breakdown of a classical Markov description of temporal correlations. In this work, we establish a direct ...

Quantum optimisation applied to the Quadratic Assignment Problem

Andrew Freeland, Jingbo Wang·Jan 3, 2026

This paper investigates the performance of the emerging non-variational Quantum Walk-based Optimisation Algorithm (NV-QWOA) for solving small instances of the Quadratic Assignment Problem (QAP). NV-QWOA is benchmarked against classical heuristics, th...

Single-Step Hybrid CV-DV Transfer of Multipartite W States Using Cat-State Qubits

Muhammad Nehal Khan, Sumrah Hussain·Jan 3, 2026

We propose a deterministic hybrid continuous-variable-discrete-variable (CV-DV) scheme for the single-step transfer of an $n$-qubit W state encoded in photonic Schr$\ddot{o}$dinger cat-state qubits within a circuit QED architecture. Logical qubits ar...

Comment on arXiv:2511.21731v1: Identifying Quantum Structure in AI Language: Evidence for Evolutionary Convergence of Human and Artificial Cognition

Krzysztof Sienicki·Jan 3, 2026

This note is a friendly technical check of arXiv:2511.21731v1. I highlight a few places where the manuscript's interpretation of (i) the reported CHSH/Bell-type calculations and (ii) Bose--Einstein (BE) fits to rank-frequency data seems to go beyond ...

Minimal length: A source of quantum non-locality

H. Moradpour, S. Jalalzadeh·Jan 3, 2026

The narrow and subtle difference between the Hilbert spaces of operators corresponding to the purely quantum mechanical momentum and the generalized momentum that includes minimal length effects is polished. Additionally, the existence of complex num...

Molchanov's Formula and Quantum Walks: A Probabilistic Approach

Hoang Vu·Jan 3, 2026

This paper establishes a robust link between quantum dynamics and classical ones by deriving probabilistic representation for both continuous time and discrete time quantum walks. We first adapt Molchanov formula, originally employed in the study of ...

Impersonating Quantum Secrets over Classical Channels

Luowen Qian, Mark Zhandry·Jan 3, 2026

We show that a simple eavesdropper listening in on classical communication between potentially entangled quantum parties will eventually be able to impersonate any of the parties. Furthermore, the attack is efficient if one-way puzzles do not exist. ...

Ground State and Collective Modes of Bose-Einstein Condensates in Newtonian and MOND-inspired gravitational potentials

Ning Liu·Jan 3, 2026

We analytically and numerically study the ground state and collective dynamics of Bose-Einstein condensates in two traps: a Newtonian potential and a logarithmic potential inspired by Modified Newtonian Dynamics (MOND). In the ground state, the MOND ...

Silicon-on-sapphire metasurfaces generate arrays of dark and bright traps for neutral atoms

Chengyu Fang, Minjeong Kim, Hongyan Mei +10 more·Jan 3, 2026

We demonstrated crystalline silicon-on-sapphire (c-SOS) metasurfaces that convert a Gaussian beam into arrays of complex optical traps, including arrays of optical bottle beams that trap atoms in dark regions interleaved with bright tweezer arrays. T...
