Inline inter-core phase control in multi-core fiber with a commercial polarization controller
Inter-core phase control is a prerequisite for interferometry in multi-core fiber (MCF), but no compact inline element for this purpose is presently available, and existing approaches require fanout…Stabilizer Learning under Global Depolarizing Noise with Polynomial Copies and $2^t$ Time
We study learning the stabilizer structure of an unknown pure $n$-qubit state observed through global depolarizing noise of unknown strength, with a fixed promised upper bound below one, using…Agentic Pipelines for Mapping Topological Codes to Quantum Hardware
Mapping a prescribed many-body Hamiltonian to a particular quantum hardware is generally an approximate process, resulting in both intended and unwanted quantum dynamics.Axion polarimetry with parametric readout: photon-number conversion and sensitivity limits
We propose a bias-assisted active photon-number conversion scheme for axion-induced polarization rotation in a four-port optical ring cavity with parametric readout.Quartet state of the neutral nitrogen-vacancy center in diamond and optimized spin readout under near-infrared two-photon excitation
Photoionization of the excited nitrogen-vacancy center (NV-) in diamond leaves the neutral defect in a metastable quartet state of unknown energy.Coherent 1-μm-Band Co-Transmission with C+L-Band Channels over 50-km Hollow-Core Fiber
We experimentally demonstrate simultaneous coherent transmission across 1-$μ$m and C+L bands, carrying $54\times125$-GBaud PDM-16QAM C+L channels and $2\times15$-GBaud PDM-QPSK 1-$μ$m channels over…Stellar wind variability in OB stars and its effect on mass-loss determinations
Virtually all stellar winds of OB stars exhibit variability in one spectral diagnostic or another.A Geometry-Informed Neural Operator surrogate of LISFLOOD-FP for rapid pluvial-fluvial flood forecasting: the case of Forlì, Italy
Physically based two-dimensional hydraulic models are too slow for real-time inundation forecasting and large ensembles.Efficient thermalization of one-dimensional noncommuting Hamiltonians via system-bath interactions with $Θ(n)$ ancilla qubits
We prove rapid convergence of a system-bath interaction algorithm for preparing Gibbs states of one-dimensional noncommuting Hamiltonians at every fixed positive temperature.Lossless propagation bounds for long-range fermionic interactions
We prove propagation estimates for extensive fermionic many-body interactions with polynomial time growth, no loss of spatial decay, and an optimal threshold for the polynomial spatial exponent.A Physics Informed Neural Network Approach to Decipher Environmental Confinement of Molecular Clouds in the Third Galactic Quadrant
Recent high-sensitivity and high-resolution surveys of the Third Galactic Quadrant [$219.75 \leq l \leq 229.75$ and $-5.25 \leq b \leq 5.25$], such as the Milky Way Imaging Scroll Painting ( MWISP)…Aberration stabilized light bullets in normal dispersion injected Kerr resonators
We investigate three-dimensional light bullets (LBs) in an optically injected, vertically emitting Kerr-Gires-Tournois interferometer operating in the normal dispersion regime.Surface charges and quantum reflection of hydrogen-isotope beams at grazing incidence
Experiments with cryogenic beams of hydrogen isotopes (hydrogen (H), deuterium (D), and tritium (T)) can be used to study quantum reflection from solid dielectric mirrors.Exceptional Points and Optimized Encoding in Qubit Stabilizer Codes
Continuous blind stabilizer measurements turn stabilizer codes into a Liouvillian spectral problem in which Hamiltonian terms compete with dissipative error channels.Fracture-Bench: A Controlled Benchmark Suite for Machine Learning Surrogates in Phase-Field Fracture Mechanics
Machine-learning surrogates are increasingly proposed to replace phase-field fracture simulations in many-query tasks such as uncertainty quantification, inverse analysis and design.On the Failure Probability of Quantum Leftover Hashing with Bad Seeds
We study hashing against quantum adversaries, as used in cryptographic applications, and provide bounds on the probability of failure in practical settings where seeds might be reused and might be…Identifying the Shear Piezoelectric Coefficient using Physics-Informed Neural Networks under Exact Boundary and Initial Constraints
The shear piezoelectric coefficient $e_{15}$ governs the shear-mode electromechanical coupling in piezoelectric micromachined ultrasonic transducers (PMUTs) and surface acoustic wave (SAW) devices…Quantum tomography on Schwartz space
In this work we show that standard results in quantum tomography, which are typically proven in the context of Hilbert spaces, can analogously be established in the theory of Schwartz spaces.Variational Functional Neural Networks (vfNN)
We present a variational functional neural network (vfNN) algorithm that optimizes physically motivated continuum functionals in integral form (e.g., Lagrangian, Hamiltonian, or free energy) to find…Unifying entanglement and nonclassicality via the Narcowich-Wigner spectrum
Entanglement and nonclassicality are two fundamental features of quantum mechanics which serve as resources in quantum information processing tasks and are tightly connected by two-mode mixing.
