Post-selected enhancement of phase sensitivity in a two-path interferometer
Post-selected metrology can exceed the standard quantum limit of single photon interference by concentrating all of the available Fisher information in a subset of post-selected outcomes.Universal Fidelity Law for Linear-Optical Entangling Gates
Imperfect photon sources degrade the performance of interference-based linear-optical entangling gates.Fluctuation-Driven Nonlinear Amplification of Quantum Statistics
Photon statistics have moved to the forefront of modern optics, as intensity fluctuations and correlations shape multiphoton interactions and reveal information beyond mean-intensity measurements.Direction-dependent magnetoelectric conductivity from dipolar topological semimetals
We compute the linear magnetoelectric conductivity of a two-band vortex nodal-ring (VNR) semimetal and a three-band Hopf semimetal (HSM) within the semiclassical Boltzmann formalism, in the…Versatile Quantum Machine Learning with an Ultra-low Power Photonic Quantum Reservoir Computer
Integrated photonic microprocessors provide high-bandwidth, massively parallel linear computation, but realizing nonlinear feature maps and temporal memory remain key challenges for machine learning.Pendellösung length-scale neutron and X-ray interferometry
Neutron and X-ray perfect-crystal interferometers (PCIs) are powerful platforms for studies of fundamental physics and phase-contrast imaging.Collective cavity quantum electrodynamics in solid-state optical clocks
Solid-state frequency standards are generally limited by strong decoherence, rendering conventional interrogation schemes inefficient.Overcoming the Hong-Ou-Mandel interference limitation for the second photon from a two-photon cascade
Quantum emitters such as semiconductor quantum dots can provide entangled photon pairs emitting from a system of cascaded states.Fisher-information training of optical sensing front ends from natural fluctuations
Fisher-information-based optimization of programmable optical front ends in situ generally requires a response model or parameter-labeled measurements.Localized Decoherence as a Constructive Tool: An Optical Simulation of Matter-Wave Interference
Decoherence is conventionally regarded as a detrimental process that suppresses quantum coherence and limits the performance of quantum technologies.Strong coupling of a reconfigurable ${}^{171}$Yb atom array to a tunable telecom-band nanofiber cavity
Nanophotonic cavities provide strong atom-photon coupling in a compact, directly fiber-coupled geometry, while a reconfigurable array of $^{171}$Yb atoms combines high-fidelity gates with a…The Chern-Simons Function and the Quantum Hall Effect
In this article, I will define the Chern-Simons invariant of a gauge connection over a three-manifold and explain some of the things that are special about it, in particular its role in…Learning-Based Reconstruction of Optical Properties in Bilayered Media from Single-distance Time-Resolved Reflectance Measurements
The inverse problem of reconstructing optical properties, specifically absorption and scattering coefficients, in layered biological media from time-domain reflectance measurements remains a…Noise-Robust Quantum State Characterization for Remote State Preparation with Deep Learning
Quantum communication underpins secure information processing and scalable quantum networks.Image-Derived PM10 Estimation in Cattle Feedlot Using Machine Learning: Addressing Concentration Ranges Beyond Existing Digital Imaging Methods
Affordable dust monitoring remains a pressing need for the cattle feedlot industry, yet camera-based PM estimation, despite its growing body of research in urban air quality settings, has not been…Human Language Shapes the Emerging Physical Reasoning in Large Language Models
Whether large language models (LLMs) acquire adequate representations of physical reality by predicting the next token remains unresolved.Automated search for highly contextual Kochen-Specker proofs
Observable-based Kochen-Specker proofs are configurations of multi-qubit Pauli observables grouped into contexts whose products are plus or minus the indentity.Enhanced thermal stability of SiGeSn by suppressing surface-mediated degradation
$\text{SiGeSn}$ alloys are promising silicon-compatible semiconductors for monolithic infrared photonics.Proximal-Only Transmission Matrix Recovery of an Arbitrarily Deformed Graded-Index Multimode Fiber
The multimode fiber is among the thinnest imaging conduits available, carrying hundreds to thousands of spatial modes through a cross-section comparable to a human hair, but its endoscopic…A Programmable Optics Cloud Laboratory
Laboratory automation can improve experimental throughput, accessibility, and reproducibility, but many robotic laboratory systems remain difficult to reconfigure.
