Quantum tunneling Mpemba effect

Hisao Hayakawa, Satoshi Takada·Jul 4, 2026

The quantum tunneling Mpemba effect is investigated within a continuous one-dimensional symmetric double-well potential open to external environmental sinks at the boundaries ($x=\pm L$). Using a non-Hermitian spectral decomposition of the effective ...

Matter-wave Induced Transparency

Tongkang wang, Yuqi Liu, Wenlan Chen +2 more·Jul 4, 2026

Electromagnetically induced transparency suppresses optical absorption through destructive interference, playing a central role in light-matter interaction and quantum information science. We report matter-wave induced transparency, where atomic coll...

A regularization method for quantum neural networks using data symmetry

Hiroshi Ohno·Jul 4, 2026

Leveraging data symmetries has recently become a key strategy in quantum neural networks (QNNs) to improve training efficiency. In this study, we propose a symmetry-informed regularization method for QNNs based on an input density matrix. By introduc...

Measurement-induced spatially nonuniform fluctuations of the local particle number and their crossover in a quasiperiodic free-fermion chain

Toranosuke Matsubara, Kazuki Yamamoto·Jul 4, 2026

We study continuously monitored dynamics of a quasiperiodic free-fermion chain defined on a Fibonacci lattice. We focus on fluctuations of the local particle number, which exhibit a spatially uniform distribution in the unitary limit. Remarkably, we ...

Perturbed quantum billiards on the hyperbolic plane

Matic Orel·Jul 4, 2026

We study the emergence of generic quantum chaos from an arithmetic billiard in the hyperbolic plane. Starting from an arithmetic triangle, we introduce small area-preserving geometric perturbations and compute long consecutive sequences of eigenvalue...

Gorini-Kossakowski-Sudarshan-Lindblad equation in different bases: application to driven-dissipative two- and multilevel systems

O. A. Ilinskaya, O. V. Ivakhnenko, A. I. Ryzhov +2 more·Jul 4, 2026

An open quantum system can be described by a master equation, of which one of the most popular is the Gorini-Kossakowski-Sudarshan-Lindblad (GKSL) equation. We revisit description of driven-dissipative quantum systems focusing on the appropriate choi...

Entanglement-Assisted Timing Optimization for Discriminating Amplitude-Damping Dynamics

Massimiliano F. Sacchi, Milajiguli Rexiti, Stefano Mancini·Jul 4, 2026

We analyze minimum-error discrimination of two qubit dynamical processes generated by phase-covariant amplitude-damping Lindbladians in a single-use scenario. The optimization involves both the input probe, possibly entangled with an isolated ancilla...

Efficient Analysis of Carrier Transport and TM-TE Emission in AlGaN UVC LEDs via Multi-band Localization Landscape Theory

Yu-Ming Chang, Ping-Jie Zhuang, Marcel Filoche +3 more·Jul 4, 2026

AlGaN-based UVC LEDs (220-250 nm) suffer from poor hole confinement and strain-induced |Z>-band dominance at high Al content (>60%), leading to increased TM emission and reduced external quantum efficiency (EQE). While conventional k.p models combine...

The influence of the transverse electric field on accelerating vortex state in the axisymmetric electric field

Ziyang Ding, Ziqiang Huang, Qi Meng +3 more·Jul 4, 2026

The relativistic vortex states of massive charged particles propagating in non-uniform axisymmetric electric field are studied. Starting from the stationary-state equation after the relativistic Foldy-Wouthuysen (FW) transformation and employing the ...

From the Hong-Ou-Mandel Effect to Quantum Sensing: Interference of Nonclassical Light with Partial Distinguishability and Noise

Matheus Eiji Ohno Bezerra·Jul 3, 2026

This thesis explores the interference of nonclassical states of light, particularly Fock and Gaussian states, in noisy linear interferometers, with applications to quantum information and quantum sensing. Using the phase-space formalism, analytical t...

OptiClear: Differentiable Curvilinear Design Rule Legalization for Inverse-Designed Photonic Devices

Hongjian Zhou, Haoyu Yang, Nicholas Gangi +3 more·Jul 3, 2026

Photonic inverse design enables ultra-compact, high-performance devices with highly curvilinear and non-intuitive geometries, but the resulting layouts often violate fabrication design rules and hinder foundry manufacturing. Legalization methods desi...

Macroscopic Quantum Interference of the Center-of-Mass Motion of Levitated Superconducting Microparticles enabled by Magnetic Higher-Order Traps

Jaume Cunill-Subiranas, Fabian Resare, Suocheng Zhao +4 more·Jul 3, 2026

We show how magnetostatic higher-order multipole traps can be used to generate macroscopic quantum interference of the motion of levitated superconducting microparticles. An appropriate combination of multipolar magnetic fields offers great versatili...

Minimal Proper Time and Deterministic Microstates: Emergent Quantum Fields and Relativistic Spacetime

Alessio Maiezza·Jul 3, 2026

We develop a top-down counterpart of the minimal proper-time formulation of quantum field theory previously introduced as an effective bottom-up framework. Starting from a deterministic pre-geometric substrate of causally ordered events, we show how ...

Device-independent Quantum Key Distribution in the commuting operator framework

Gereon Koßmann, René Schwonnek, Po-Chieh Liu +1 more·Jul 3, 2026

Device-independent quantum key distribution (DIQKD) is arguably the gold standard for secure quantum communication, as it aims to rely only on observed input-output statistics of an uncharacterized device which is only assumption to obey the laws of ...

A Pulsed Live-Cell Quantum Microscope for Entangled Solid State and Biological Qubits

Javier Noé Ramos-Silva, Sangjun Noh, Minghao Jiang +5 more·Jul 3, 2026

Two revolutions in quantum sensing are converging on the same microscope stage. Biological qubits have emerged as genetically encoded, optically addressable quantum systems inside live cells. Solid state spin based qubits have been entangled and used...

Comparing and learning figures of merit for quantum circuit compilation

Harshdeep Singh, Marvin Richter, Mats Granath +1 more·Jul 3, 2026

To make quantum algorithms executable on a particular quantum device, they need to be compiled into circuits that respect constraints of the quantum hardware. This compilation usually involves multiple steps, where many hardware-compatible circuits a...

Generating one-way computations with flow: flow-preserving rewriting that ignores the interpretation

Miriam Backens·Jul 3, 2026

The one-way model is a universal model of quantum computation, driven by successive adaptive single-qubit measurements on an entangled resource state. Measurements are non-deterministic, yet if the computation satisfies one of several related familie...

On the emergence of quantum many-body chaos for tunably-broken integrability

Sounak Biswas, Sthitadhi Roy, Roderich Moessner·Jul 2, 2026

We develop a quantitative theory for the emergence of quantum many-body chaos as integrability is broken via a tunable parameter. In a circuit model of free fermions, 'doped' with a tunable density of integrability-breaking gates, we uncover the micr...
