Silicon-based Josephson junction field-effect transistors enabling cryogenic logic and quantum technologies
Yusheng Xiong, Kaveh Delfanazari·Oct 29, 2025
The continuous miniaturisation of metal-oxide-semiconductor field-effect transistors (MOSFETs) from long- to short-channel architectures has advanced beyond the predictions of Moore's Law. Continued advances in semiconductor electronics, even near cu...
Low-Gap Hf-HfOx-Hf Josephson Junctions for meV-Scale Particle Detection
Y. Balaji, M. Surendran, X. Li +7 more·Oct 29, 2025
Superconducting qubits have motivated the exploration of Josephson-junction technologies beyond quantum computing, with emerging applications in low-energy photon and phonon detection for astrophysics and dark matter searches. Achieving sensitivity a...
The Phase-Coupled Caldeira-Leggett Model: Non-Markovian Open Quantum Dynamics beyond Linear Dissipation
Ao-Xiang Chang, Yu Su, Zi-Fan Zhu +3 more·Oct 29, 2025
We introduce the \textit{Phase-Coupled Caldeira-Leggett} (PCL) model of quantum dissipation and develop an exact framework for its dynamics. Unlike the conventional Caldeira-Leggett model with linear system-bath coupling $H_{\mathrm{SB}}\propto\hat F...
Properties and Applications of Partially Deterministic Polytopes
Marwan Haddara, Howard M. Wiseman, Eric G. Cavalcanti·Oct 29, 2025
The assumption of a deterministic local hidden variable model constrains the experimentally accessible statistics in a Bell experiment to be contained in the Bell-local polytope. But what if the outputs for only a subset of the measurements at each s...
Generalized Dynamical Duality of Quantum Particles in One Dimension
Yu Chen, Xiaoling Cui·Oct 29, 2025
We prove a generalized dynamical duality for identical particles in one dimension (1D). Namely, 1D systems with arbitrary statistics -- including bosons, fermions and anyons -- approach the same momentum distribution after long-time expansion from a ...
Geometric and Orbital Control of Correlated States in Small Hubbard Clusters
Shivanshu Dwivedi, K. Palandage·Oct 29, 2025
Arrays of semiconductor quantum dots provide a powerful platform to design correlated quantum matter from the bottom up. We establish a predictive framework for engineering local electron pairing in these artificial molecules by systematically deploy...
Engineering chlorine-based emitters in silicon carbide for telecom-band quantum technologies
A. N. Anisimov, A. V. Mathews, K. Mavridou +3 more·Oct 28, 2025
We report the experimental realization and optical characterization of chlorine-vacancy (ClV) color centers in 4H-SiC emitting in the fiber-optic telecom bands. These defects are created via chlorine ion implantation followed by high-temperature anne...
Group theoretic quantization of punctured plane
Manvendra Somvanshi, D. Jaffino Stargen·Oct 28, 2025
We quantize punctured plane, $X=\mathbb{R}^2-\{0\}$, employing Isham's group theoretic quantization procedure. After sketching out a brief review of group theoretic quantization procedure, we apply the quantization scheme to the phase space, $M=X \ti...
Universal Limits on Quantum Correlations
Samuel Alperin·Oct 28, 2025
Quantum correlations are the singular, defining resource of quantum information science and metrology, forming the basis of every operational advantage that quantum systems hold over classical ones. Yet exact bounds on these correlations-such as the ...
Gouy Phase-Related Effects in the Free-Space Optical Modulation of Free Electrons
Zhexin Zhao, Yiqi Fang, Mevlana Yunus Uludağ +1 more·Oct 28, 2025
Modulating the free-electron wave function with light brings new opportunities to create attosecond electron pulse trains, to probe the quantum coherence of systems with significantly improved spatial resolution, and to generate classical and non-cla...
Observation of vector rogue waves in repulsive three-component atomic mixtures
G. A. Bougas, G. C. Katsimiga, S. Mossman +3 more·Oct 28, 2025
We report the experimental observation of vector extensions of Peregrine solitons in highly particle-imbalanced, pairwise immiscible three-component repulsive Bose-Einstein condensates (BECs). The possibility of an effectively attractive character of...
Classically Prepared, Quantumly Evolved: Hybrid Algorithm for Molecular Spectra
Alessandro Santini, Stefano Barison, Filippo Vicentini·Oct 28, 2025
We introduce a hybrid classical-quantum algorithm to compute dynamical correlation functions and excitation spectra in many-body quantum systems, with a focus on molecular systems. The method combines classical preparation of a perturbed ground state...
Quantifying Unextendibility via Virtual State Extension
Hongshun Yao, Jingu Xie, Xuanqiang Zhao +3 more·Oct 28, 2025
Monogamy of entanglement, which limits how entanglement can be shared among multiple parties, is a fundamental feature underpinning the privacy of quantum communication. In this work, we introduce a novel operational framework to quantify the unshare...
Structure, Optimality, and Symmetry in Shadow Unitary Inversion
Guocheng Zhen, Yu-Ao Chen, Mingrui Jing +3 more·Oct 28, 2025
Reversing unitary operations is a key task in quantum computing and quantum control. In this work, we introduce and develop the framework of shadow unitary inversion, a relaxed variant of unitary inversion in which the goal is to reproduce the action...
A Euclidean Monte-Carlo-informed route to ground-state preparation for quantum simulation of scalar field theory
Navya Gupta, Christopher David White, Zohreh Davoudi·Oct 28, 2025
Quantum simulators hold great promise for studying real-time (Minkowski) dynamics of quantum field theories. Nonetheless, preparing non-trivial initial states remains a major obstacle. Euclidean-time Monte-Carlo methods yield ground-state spectra and...
Spin Glass Dynamics on Complex Hardware Topologies: A Bond-Correlated Percolation Approach
Viviana Gómez, Gabriel Téllez, Fernando J. Gómez-Ruiz·Oct 28, 2025
Understanding how frustration and disorder shape relaxation in complex systems is a central problem in statistical physics and quantum annealing. Spin-glass models provide a natural framework to explore this connection, as their energy landscapes are...
Pairing-induced phase transition in the non-reciprocal Kitaev chain
Pietro Brighi, Andreas Nunnenkamp·Oct 28, 2025
Investigating the robustness of non-reciprocity in the presence of competing interactions is central to understanding non-reciprocal quantum matter. In this work, we use reservoir engineering to induce non-reciprocal hopping and pairing in the fermio...
Frustration-Free Control and Absorbing-State Transport in Entangled State Preparation
T. Dörstel, T. Iadecola, J. H. Wilson +1 more·Oct 28, 2025
We study frustration-free control, a measurement-feedback protocol for quantum state preparation that extends the concept of frustration-free Hamiltonians to stochastic dynamics. The protocol drives many-body systems into highly entangled target stat...
Neutrino thermalization via randomization on a quantum processor
Oriel Kiss, Ivano Tavernelli, Francesco Tacchino +2 more·Oct 28, 2025
The dynamical evolution of neutrino flavor in supernovae can be modeled by an all-to-all spin Hamiltonian with random couplings. Simulating such two-local Hamiltonian dynamics remains a major challenge, as methods with controllable accuracy require c...

Lei Gioia, Sanjay Moudgalya, Olexei I. Motrunich·Oct 28, 2025
The construction of parent Hamiltonians that possess a given state as their ground state is a well-studied problem. In this work, we generalize this notion by considering simple quantum states and examining the local Hamiltonians that have these stat...
