Relativistic Strong Quantum Mpemba Effect
The Unruh effect links acceleration to thermalization, providing a relativistic setting for anomalous quantum relaxation.Enhanced orbital-angular-momentum dimensionality and spatial-spectral decoupling in thin-film SPDC
Thin-film spontaneous parametric down-conversion, due to the relaxed phase-matching condition, generates photon pairs that are extremely broadband in frequency and angle and highly entangled in…Microscopically informed self-consistent multi-resolvent closure for dense many-body spectra
The exact multi-resolvent hierarchy of dense many-body spectra encodes higher-order spectral-weight correlations, but closing it predictively for interacting Hamiltonians remains a challenge.Optimal Quantum-Circuit Synthesis and Implementation of General Unitaries with Parallelized Bitstring-Conditioned Rotations
We theoretically introduce a quantum-circuit synthesis protocol to realize any $n$-qubit transformation $U\in U(2^n)$, up to a diagonal.A $q$-Inspired Radial Quantum Kinematics
We study how the one-dimensional deformation suggested by nonadditive $q$-calculus can be extended to a rotationally covariant quantum model and what observable consequences follow from this…Measurement incompatibility in Bayesian quantum estimation beyond quadratic loss
In single-shot Bayesian multiparameter quantum estimation, measurement incompatibility can increase the minimum joint quadratic loss by at most a factor of two relative to the bound obtained by…The family of Tietz potentials
We show that several potential-energy functions based on the exponential function $e^{-αr}$, $α> 0$, are either equivalent or identical to the Tietz potential.Polarization signatures of mixed scalar - pseudoscalar ALP - photon couplings in intense laser pulses
We investigate photon-to-axion-like-particle (ALP) conversion in a finite, linearly polarized laser pulse for a single ALP field with simultaneous scalar-type and pseudoscalar-type couplings to…Enhancement of Li and Na Storage in Janus HfSSe Monolayers by Co-Induced Electron-Deficient Chalcogen Sites: A First-Principles Study
The growing demand for high-capacity, fast-charging, and durable rechargeable batteries has intensified the search for advanced electrode materials, with two-dimensional materials offering large…Dimension-free marginal inequalities for pure three-party states
The quantum marginal problem, concerned with the compatibility of local and global properties of a multipartite quantum system, is arguably one of the fundamental questions in quantum theory.Black Holes are about Quantum Information
We review and analyse quantum information-theoretic approaches to black hole evaporation that purport to bring us closer to a resolution of the black hole information paradox.Parallel Teleportation via AME(5,2) States on IBM Quantum Hardware
The five-qubit Absolutely Maximally Entangled AME$(5,2)$ state, whose every pair of qubits is maximally mixed so that all its information lives in non-local correlations, could in principle serve as…Structured light for addressable two-qubit gates in medium-sized ion crystals: modeling motional and dephasing errors
Geometric phase gates with addressed laser radiation are widely used in trapped-ion quantum computers to drive high-fidelity entangling gates on an arbitrary qubit pair of a larger ion chain.Dynamical Mean-Field Theory for Real Materials using Variational Quantum Compressed Time Evolution on a Quantum Computer
We design a hybrid quantum-classical computational workflow, combining density functional theory and dynamical mean-field theory, to investigate the electronic properties of CaCuO2, a parent…Observable-Level Framework for Finite-Key Security in Coherent-One-Way Quantum Key Distribution
Practical security analysis of Coherent-One-Way (COW) quantum key distribution requires optical-device modeling, finite experimental statistics, and security inference to be treated consistently…Dynamics of two bosons with density-assisted tunnelling in a one-dimensional tilted lattice
We investigate the dynamics of two bosons in a tilted one-dimensional optical lattice with both standard and density-assisted tunnelling.Ensemble basis-free coherence for quantum communication
The resource theory of coherence quantifies the quantum properties of states and their role in quantum information processing.Floquet ground state order
Clean, interacting, periodically driven systems are believed to thermalize to featureless, infinite-temperature states that preclude the formation of stable ordered states.Quantum Broker: QoS-Aware Distribution of Quantum Computations
Cloud-accessible quantum computing has made heterogeneous Quantum Processing Units (QPUs) available through provider platforms that differ in qubit technology, calibration state, queueing behavior…CO$Φ$ - COmpiling PHotonics into dIgital quantum circuits
Photonic and qubit-based (digital) approaches to quantum computing are largely regarded as separate paradigms.
