Quantum Nonlocal Games on Graph Ensembles
Joshua Tucker, Chris Weeks, Peter Drmota +11 more·Jun 15, 2026
Quantum entanglement is one of the most striking discoveries in all of science. This effect allows, for instance, two spatially separated agents to coordinate their actions, without communication, to an extent that is both counter-intuitive, and prov...
Charging Quantum Batteries with Chiral Squeezing
Borhan Ahmadi, André H. A. Malavazi, Janine Splettstoesser +2 more·Jun 15, 2026
We propose a quantum-battery charger based on a driven bosonic Kitaev chain (BKC), where chiral squeezing converts passive input fluctuations into ordered, non-passive battery states. While a coherent input pulse exhibits phase-sensitive chiral trans...
Scalable generation of heralded single photons via active feed-forward switching of a fiber delay line
Xavier Barcons Planas, Helen M. Chrzanowski, Janik Wolters·Jun 15, 2026
Quasi-deterministic single-photon generation is a key requirement for many photonic quantum technologies. Photon sources based on spontaneous parametric down-conversion (SPDC) are widely used for producing high-quality photons; however, the probabili...
Complete entanglement detection using polynomial invariants
Thomas C. Fraser, Vjosa Blakaj, Roberto Rubboli +2 more·Jun 15, 2026
Existing methods for deciding whether a bipartite quantum state is separable or entangled typically fall into one of two categories: they are either complete but require access to an explicit density matrix followed by numerical optimization, or they...
High-dimensional coherence to entanglement transduction under canonical noise
Asad Ali, Aiham M. Rostom, Saif Al-Kuwari +3 more·Jun 15, 2026
We develop an analytical framework for coherence-to-entanglement conversion in bipartite high-dimensional quantum systems, so-called qunits. An arbitrary coherent input qunit is coupled to an incoherent ancilla through a generalized controlled-shift ...
Ultrastrongly coupled open systems and fine grained time
Stefano Marcantoni, Marco Merkli·Jun 15, 2026
We study the dynamics of a d-level quantum system coupled to a bosonic reservoir when the coupling constant is large. It is known that in the limit of infinite coupling strength, the system undergoes an instantaneous nonselective measurement, resulti...
Quantum enhancement and Doppler suppression of Kasevich-Chu atom interferometer with motional squeezing states
Dongyang Yu, Yubin Wang, Fong En Oon +1 more·Jun 15, 2026
Hybridization of internal and external atomic degrees of freedom in a Kasevich-Chu interferometer enables the possibility to enhance the sensitivity significantly even under quantum-standard limit. By introducing motional squeezing state as an input,...
Fuzzy-processing quantum computation
Yan-Xiong Du·Jun 15, 2026
Quantum computation has attracted numerous attentions and develops rapidly in the recent decades. To against the decoherence and the control errors upon the qubits, quantum error corrections are adopted. Such approaches require lots of redundant qubi...
Electronic Band Structure of Silicon Determined via a Variational Adiabatic Eigensolver: Theory and Experiment
Xingrui Liu, Liyang Sui, Tianqi Cai +11 more·Jun 15, 2026
This work addresses the critical challenge of excited-state preparation for semiconductor band structure calculations. We introduce a variational adiabatic eigensolver (VAE) protocol that combines adiabatic evolution with variational optimization to ...
Ultracold atomic lattice systems for simulating topological phases: A review
Bei-Bei Wang, Xiao-Dong Lin, Jinyi Zhang +1 more·Jun 15, 2026
Owing to rapid recent progress, ultracold atomic lattice systems for simulating topological phases are now at a pivotal stage, evolving from established paradigms into increasingly versatile and programmable quantum simulators. In this review, we sur...
What does measuring one qubit reveal about another? $K$-networks as a directed diagnostic for quantum circuits
Kostas Blekos, Paulo Vitor Itaboraí·Jun 15, 2026
Many-qubit circuit states are hard to inspect directly, so they are often summarized by pairwise graph weights. Common pairwise weights report symmetric correlations, while many circuit questions are directed and basis-specific: if qubit $i$ is measu...
Preparation of Fractional Quantum Hall States on Quantum Computers
Hao Wu, Lei-Yi-Nan Liu, Zhao-Xin Pei +4 more·Jun 15, 2026
The realization of fractional quantum Hall (FQH) states, characterized by fractional charge and intrinsic topological order, on quantum computers represents a central challenge at the interface of condensed matter physics and quantum information scie...
Phase controlled spectral topology, dynamic stability and sensitivity in Non-Hermitian Cavity Magnonics
Sachin Singh Bargahi, Rajeev Singh, Biswanath Bhoi·Jun 15, 2026
We theoretically investigate a non-Hermitian cavity-magnon platform in which coherent photonmagnon interactions and reservoir-mediated dissipative coupling interfere through a single externally tunable phase. We show that this interference phase prov...
Fully Quantum Algorithm for the 1-dimensional linear Lattice Boltzmann Method
Mohammed Bediche, Matthijs van Waveren, Denis Ricot +1 more·Jun 15, 2026
A fully quantum algorithm for solving the one-dimensional linear advection-diffusion equation using the Lattice Boltzmann method as a numerical procedure is presented in this work. We start by presenting a state of the art of the current usage of qua...
GreenBox: Prototyping of an Automatic Road Accident Detection System with Real-Time Notification SMS
Júlio Rocha, Salviano Soares, António Valente +1 more·Jun 15, 2026
The Internet of Things (IoT) project, called "GreenBox", proposes the development of a prototype for the detection of road accidents, using sensors and actuators connected to an Arduino Uno and a Global System for Mobile Communications (GSM) card wit...
Impact of ADAS and V2X Penetration Rates on Cooperative Active Safety
M. C. Lucas-Estañ, B. Coll-Perales, M. I. Khan +2 more·Jun 15, 2026
A major driver of connected and automated driving is cooperative active safety. The effectiveness of cooperative safety applications depends on the ability of vehicles to detect traffic safety risks in advance. Such risks can be identified either thr...
Detecting basis-dependent hardware errors through spatio-temporal quantum steering
Hsiang-Wei Huang, Kuo-Feng Chiu, Yi-Te Huang +3 more·Jun 15, 2026
Spatio-temporal quantum steering provides a framework for benchmarking the nonclassicality of general quantum state transfer processes. A central diagnostic is the no-signaling-in-time (NSIT) condition, whose violation can indicate basis-dependent ha...
Worst-case depth hierarchy for shallow quantum circuits
Min-Hsiu Hsieh, Michael de Oliveira, Sathyawageeswar Subramanian +1 more·Jun 15, 2026
Circuit depth is a central resource in complexity theory. While bounded-depth classical circuits admit well-understood hierarchy theorems, the internal structure of constant-depth quantum computation remains comparatively unexplored. We prove an expl...
Real-space spectral functions of three-dimensional billion-size topological non-Hermitian matter with tensor networks
Yitao Sun, Jose L. Lado, Guangze Chen·Jun 15, 2026
Non-Hermitian systems host a wide range of unconventional topological phenomena while large-scale simulations in finite three dimensional systems remain challenging because of the rapidly growing number of sites. In particular, higher-order topologic...
