Ghost unitaries for loss-resilient photonic resource-state generation
Entangled few-photon states, such as Bell and Greenberger-Horne-Zeilinger (GHZ) states, are central resources for discrete-variable photonic quantum information processing.Optical interferometric tools for probing memory effects
Recent efforts to detect non-Markovian memory have become increasingly important, motivated by the broad relevance of memory effects in quantum information processing, metrology, and thermodynamic…Krylov Complexity and Quantum Many-body Scars in Non-Hermitian Kinetically Constrained Models
Thermalization in closed quantum systems and its breakdown are central to understanding the emergence of statistical behavior in isolated many-body systems.Generating Superposition of Transverse Ising Ground States by Quantum Interaction
We investigate superpositions of quantum Ising ground states generated through a quantum interaction, in which the nearest-neighbor coupling strength is promoted to an operator acting on a central…QGrAT: Quantum Grade-Aware Transformer for Jet Tagging
Lorentz symmetry and the three-prong structure of hadronic top decays provide physical guidance for designing compact quantum jet taggers.Periodic-Pulse Control of Collective Emission and Photon Statistics in Interacting Quantum Emitters
We investigate the collective emission spectra and photon correlations of two identical dipole-dipole-coupled emitters under continuous-wave (CW) and periodic pulsed driving.A Controlled Null Result for Per-Gate Riemannian Optimization in VQE
Parametrized gates in a variational quantum eigensolver (VQE) live on a product of unitary groups, which makes Riemannian optimization a natural candidate for improving training.Distributed quantum phase sensing using an SU(1,1) Perelomov coherent state in a Mach-Zehnder interferometer network
We present a theoretical study of distributed quantum sensing using a reconfigurable network of $N$ Mach--Zehnder interferometers to simultaneously estimate weighted linear combinations of relative…Norm properties of quantum uniformity measures
We prove that for $k=4$ the quantum uniformity measures are norms, whereas for every $k\geq5$ the triangle inequality fails.Imaging the topological sign of a Dirac mass with spin-polarized tunneling
A Dirac mass is characterized not only by its magnitude but also by its sign, which influences the Berry curvature, Hall response, and the propagation direction of chiral boundary modes.Time-Domain Observables for Resonant Scattering in Quantum Simulations of Lattice Gauge Theory
Quantum computing may allow unprecedented access to nonequilibrium quantum dynamics, including problems of interest in particle physics, like the real-time development of scattering processes.Mathematical framework for simulation of non-perturbative cavity optomechanics with plate-like dielectrics
Cavity optomechanical models typically treat a sensor either as a perturbative polarizable object in a pre-existing optical field, or solve the field at a fixed equilibrium and linearize in a fixed…An Aubry-André localized optical lattice clock
Optical lattice clocks in space could improve satellite navigation systems and enable new tests of fundamental physics, including gravitational-wave detection and tests of relativity.A three-eighths upper bound on the stabilizer-rank exponent of face-center magic states
We give an explicit construction proving that the exact stabilizer rank of $m$ copies of the qubit face-center magic state is $O(2^{3m/8})$.QMBL: the Quantum Many-Body Leaderboard. A live record of published ground-state energies for lattice Hamiltonians
In condensed matter physics, scientists explore phase diagrams of matter through various methods (analysis, numerics, experiment) and achieve consensus when enough methods agree.Primordial Graviton Entanglement in Quasicrystalline Inflation
We study the entanglement structure of gravitons in quasicrystalline inflation.Rydberg Atomic Quantum Receivers for OFDM Systems: An Atomic-Comb Design
Rydberg atomic quantum receivers (RAQR) exhibit exceptional sensitivity to radio-frequency (RF) signals, positioning them as promising candidates for next-generation wireless systems.Photonic realization of an electromagnetic cavity field with uniform mirror motion
We perform a detailed mathematical study of the effective Hamiltonian describing a non-stationary electromagnetic cavity field, introduced by C.~K.~Law, in the presence of uniform linear motion.Receiver-Constrained Recovery Placement for Encoded-Qutrit Teleportation under Monitored Decay
Using established probabilistic measurement-reversal theory, we study recovery placement in encoded-qutrit teleportation under monitored decay.Criticality Concentrates Extensive Sensing Information into a Local Readout
We show that criticality concentrates extensive sensing information into a local trajectory.
