Structured leakage in OAM-encoded qubits revealed by distributed quantum feature extraction
Orbital angular momentum (OAM) modes have emerged as an important platform for high-dimensional quantum communication but remain vulnerable to environmental noise and channel imperfections.Squeezed light from a semiconductor amplifier
The possibility of generating light in a squeezed quantum state during saturated light amplification in a semiconductor amplifier is theoretically analyzed.RACE-FPP: A Robust AI-assisted Characterisation Enhancement for Fringe Projection Profilometry
Fringe Projection Profilometry (FPP) requires precise system characterisation to achieve reliable three-dimensional (3D) reconstructions; however, characterisation accuracy strongly depends on…Boosting the photon bunching of classical light via a modified Fabry-Pérot cavity
We proposed to boost the photon bunching effect of classical light via a modified Fabry-Pérot cavity with one of the cavity mirrors being replaced by a spatial light modulator, through which…PolarScale: A Physics-Grounded Benchmark for Radiometrically Consistent RGB-to-Stokes Estimation
Polarization imaging provides physical cues beyond intensity imaging but typically requires specialized hardware.Energy-constrained two-way capacity bounds for noisy Gaussian channels
A gap between achievable rates and converse bounds persists for energy-constrained bosonic communication in the presence of excess noise.Constraints on the Origin of Universal $1/f^2$ Photon-Count Spectra at Baseband
A series of 11.6-d-duration photon-counting experiments, employing a broad variety of light sources with different statistical properties and optical spectra, were carried out over a 1.5-yr period.A robust framework for the comprehensive characterisation of parametric down-conversion sources
Reliable verification of squeezed-light sources is essential for photonic quantum technologies.Spatial delocalization of cold oscillators in hollow-core fibers
Trapped particles in hollow-core fibers enable long-range sensing, though advanced control of their in-fiber motion, such as multimodal cooling and squeezing, remains challenging.Electro-Optical Metalens for Near-Surface Cooling of a Levitated Particle
Advanced levitation optomechanics in the quantum regime requires sophisticated quantumengineered protocols operating at shorter length and time scales, demanding an increasing control over both…Energy-constrained two-way capacities of pure-loss and quantum-limited amplifier channels
We determine the two-way quantum, entanglement-distribution, private, and secret-key capacities of the pure-loss bosonic channel under an unconditional mean transmitted-photon-number constraint.Targeted search shows that random-device testing underestimates worst-case error in a simulated wave-based neural operator
Wave-based processors promise fast, energy-efficient Fourier layers for neural operators.Spin-orbit-induced gauge field and spin Hall effects in quasi-paraxial fluids of light
We show that quasi-paraxial fluids of light propagating in nonlinear Kerr media naturally experience an effective gauge field arising from the intrinsic spin-orbit interaction of light encoded in…Origin of the inhomogeneous linewidth in a solid state $^{229}$Th:CaF$_2$ nuclear clock
Narrow linewidth (high-Q) quantum discriminators are essential for realizing solid-state $^{229}$Th nuclear clocks, yet the observed transition linewidths remain at the tens-to-hundreds-of-kilohertz…Symmetry resolved entanglement in Schwinger pair production
We study the charge resolved structure of the pairwise mode entanglement produced by the Schwinger effect.Self-organized Layered Structures of Nitrogen-Vacancy Centers with Preferential Orientation in Heteroepitaxial Diamond Films
Here, we report the fabrication and characterization of single crystal diamond films on a two-inch wafer-scale containing three-dimensional layered structures of negatively charged nitrogen-vacancy…Stimulated Parametric Down-Conversion: From Foundational Coherence to Structured Light Applications
Stimulated parametric down-conversion (StimPDC) is the seeded version of the process that underlies much of photonic quantum information.Pathway-resolved analysis of internal conversion enabled by Gaussian boson sampling
Gaussian Boson Sampling (GBS) has provided strong evidence of quantum advantage, motivating the search for real-world applications.Mode-tunable inter-core coupling of photon-number-resolved quantum light in a telecom multicore fiber
Multicore optical fibers (MCFs), developed to scale classical telecommunications, are gaining traction as a quantum platform for high-dimensional key distribution, entanglement, and photonic quantum…Comment on ''Chiral electromagnetic surface waves on Chern-Simons interfaces'' Phys.Rev.D114(2026)L051903 and on arXiv:2606.12513 by N. Kaloper
We demonstrate that Maxwell electrodynamics interacting with a planar Chern-Simons interface does not have plane wave solutions localized on the interface.
