Robust Universal Photon Blockade in a Bimodal Jaynes-Cummings Model via Kerr Nonlinearity
Guohao Chang, Hunduz Halemjan, Shangyun Liu +2 more·Apr 4, 2026
Universal photon blockade in a two-mode Jaynes-Cummings model incorporating third-order Kerr nonlinearity is demonstrated with a single two-level atom coupled to a waveguide microcavity. Realization of this universal photon blockade is attributed to ...
Entanglement generation from gravitationally produced massless vector particles during inflation
Alessio Belfiglio, Mattia Dubbini, Orlando Luongo·Apr 4, 2026
We study the gravitational production of spectator massless vector particles in a single-field inflationary scenario, and the related entanglement generation across the Hubble horizon. Accordingly, we consider a quasi-de Sitter background evolution, ...
GPU-Accelerated Quantum Simulation: Empirical Backend Selection, Gate Fusion, and Adaptive Precision
Poornima Kumaresan, Pavithra Muruganantham, Lakshmi Rajendran +1 more·Apr 4, 2026
Classical simulation of quantum circuits remains indispensable for algorithm development, hardware validation, and error analysis in the noisy intermediate-scale quantum (NISQ) era. However, state-vector simulation faces exponential memory scaling, w...
Interaction with the Environment via Random Matrices and the Emergence of Classical Field Theory
Alexey A. Kryukov·Apr 4, 2026
It was recently shown that Newtonian dynamics of macroscopic particles can be derived from unitary Schrödinger evolution under an assumption on the system-environment interaction, namely that the interaction Hamiltonian effectively exhibits a random-...
Quantum effects in plasmas
M. Bonitz, H. Kählert, D. Krimans +11 more·Apr 4, 2026
The year 2025 had been designated by UNESCO as the International Year of Quantum Science and Technology. 125 years ago Max Planck's discovery of radiation quanta started the quantum era and 100 years ago quantum mechanics was discovered by Schroeding...
How Events Separated by a Timelike Interval Can Help Us Understand Quantum Nonlocality
Luiz Carlos Ryff·Apr 4, 2026
Quantum entanglement plays a fundamental role in quantum cryptography and computation. An important example of quantum entanglement can be found in the correlations of Einstein, Podolsky, and Rosen (EPR). However, despite the plethora of articles rel...
Ground-state selection via nonlinear quantum dissipation
Alireza Ataei, Olle Eriksson, Vahid Azimi Mousolou·Apr 4, 2026
Finding the ground state of complex quantum systems remains a central challenge in many-body physics, quantum chemistry, and combinatorial optimization, due to the exponential growth of the Hilbert-space dimension and the entangled structure of groun...
Spatial Localization of Relativistic Quantum Systems: The Commutativity Requirement and the Locality Principle. Part I: A General Analysis
Valter Moretti·Apr 4, 2026
We investigate whether commutativity is necessary to represent relativistic locality for localization observables of relativistic quantum systems in Minkowski spacetime. A well known no-go theorem by Halvorson and Clifton shows that commutativity of ...
Leakage Suppression in Quantum Control via Static Parameter Offsets
Ting Lin, Zi-Hao Qin, Zheng-Yuan Xue +1 more·Apr 4, 2026
High-fidelity quantum operations require the system dynamics to be strictly confined to the computational subspace. In practice, however, control fields inevitably couple to leakage levels, giving rise to quantum state leakage that significantly redu...
Quantum Algebraic Diversity: Single-Copy Density Matrix Estimation via Group-Structured Measurements
Mitchell A. Thornton·Apr 4, 2026
We extend the algebraic diversity (AD) framework from classical signal processing to quantum measurement theory. The central result -- the Quantum Algebraic Diversity (QAD) Theorem -- establishes that a group-structured positive operator-valued measu...
Robust self-testing with CHSH mod 3
Igor Klep, Nando Leijenhorst, Victor Magron·Apr 4, 2026
The CHSH mod 3 Bell inequality is a natural testbed for higher-dimensional quantum nonlocality, yet its maximal quantum violation and self-testing properties have remained unresolved. We determine its exact maximal quantum value and show that, up to ...
Random matrix theory of integrability-to-chaos transition
Ben Craps, Marine De Clerck, Oleg Evnin +1 more·Apr 4, 2026
The statistics of gaps between quantum energy levels is a hallmark criterion in quantum chaos and quantum integrability studies. The relevant distributions corresponding to exactly integrable vs. fully chaotic systems are universal and described by t...
Quantum Realization of the Wallis Formula
Bin Ye, Ruitao Chen, Lei Yin·Apr 4, 2026
We present a unified quantum-mechanical derivation of the Wallis formula from two solvable radial systems: the circular states of the three-dimensional isotropic harmonic oscillator and the lowest-radial-branch states of the planar Fock--Darwin probl...
Superradiant phase transition in cavity magnonics via Floquet engineering
Si-Yan Lin, Fei Gao, Ye-Jun Xu +4 more·Apr 4, 2026
We propose a scheme to engineer the superradiant phase transition (SPT) in cavity magnonics by periodically modulating the frequency of the magnon mode. The studied system is composed of a yttrium iron garnet (YIG) sphere positioned inside a microwav...
Nonlocal advantage of quantum imaginarity in Schwarzchild spacetime
Bing Yu, Xiao-Yong Yang, Xiao-Li Hu +2 more·Apr 4, 2026
Black hole spacetimes provide a natural setting for quantum systems in curved spacetime, where effects such as Hawking radiation arise from event horizons. In this work, we investigate the impact of the Hawking effect on quantum imaginarity in Schwar...
Interaction of twisted light with free twisted atoms
I. Pavlov, A. Chaikovskaia, D. Karlovets·Apr 4, 2026
We investigate absorption and scattering of structured light by atoms, treating the photon and the atomic center of mass as spatially localized wave packets. We show that vortex photons can transfer orbital angular momentum (OAM) to the atomic center...
Moving Detector Quantum Walk with Random Relocation
Md Aquib Molla, Sanchari Goswami·Apr 4, 2026
We study a discrete-time quantum walk in presence of a detector at $x_D$ initially. The detector here is repeatedly removed after a span of $t_R$, the removal time, and reinserted at random locations. Two relocation rules are considered here: In Mode...
Unambiguous arbitrary high-dimensional Bell states analyzer via indefinite causal order
Jun-Hai Zhao, Wen-Qiang Liu, Hai-Rui Wei·Apr 4, 2026
High-dimensional quantum systems greatly outperform their two-dimensional counterparts in channel capacity, quantum complexity and efficiency, quantum communication security, etc. Bell-state analyzer (BSA) is a crucial prerequisite for a number of qu...
Disorder-Induced Exponential Scaling of Subradiant Decay Rates
Guoqing Tian, Xin-You Lü·Apr 4, 2026
Subradiance, a hallmark cooperative phenomenon in waveguide QED, is characterized by a universal power-law scaling of decay rates with system size and underpins many applications in quantum information storage. Here, we demonstrate that disorder driv...
Impure codes exceeding the pure bounds for quantum local recovery
Carlos Galindo, Fernando Hernando, Helena Martín-Cruz +1 more·Apr 4, 2026
Literature provides several bounds for quantum local recovery, which essentially consider the number of message qudits, the distance, the length, and the locality of the involved codes. We give a family of $J$-affine variety codes that result in impu...
