Operational theory for photonic circuits: generalizing linear optics beyond quantum theory
We use the analogy between the quadrature operators in quantum optics and the phase-space coordinates in a mechanical harmonic oscillator to generalise the theory of linear optics beyond quantum…Optical Fourier Architecture for Universal Nonlinear Functions
We introduce an exact algebraic architecture that evaluates an arbitrary finite Fourier series using a two-mode ($2 \times 2$) linear optical circuit, with the only tunable components being…Multistate Torsion in Zitterbewegung
We derive nonlinear Zitterbewegung velocity of electrons augmented by band torsion in crystals.Attosecond correlation interferometry
Correlations between optical modes, ranging from classical fluctuations to quantum entanglement, are a cornerstone of modern optics and emerging quantum technologies.Density Matrices of Pulsed Quantum Light
Pulsed light is represented by density matrices whose correlation functions have different properties of stationarity and coherence.Multimode radiation pressure actuation of a mechanical resonator using a spatial mode sorter
Multimode optomechanical scattering is ubiquitous in free-space imaging protocols, but its radiation pressure counterpart is challenging to detect with extended objects.Interferometric Readout of Momentum-Space Topology in a Programmable Dissipative Photonic Circuit
Topology under non-Hermitian dynamics is encoded in the phase of the bulk evolution, yet strong dissipation suppresses the amplitudes carrying it.Input-output formulation of quantum light spectroscopy
We develop an input-output formulation of quantum light spectroscopy (QLS) by combining the input-output theory, commonly used in quantum optics, with the perturbative expansion method for nonlinear…Normal-ordered perturbative expansion for matter systems interacting with continuous-mode quantum photon fields
We develop a normal-ordered perturbative expansion method to compute the reduced dynamics of a matter system interacting with a general continuous-mode photon field state.LensBridge: Frequency-Guided Compound Degradation Adaptation for Lens Aberration Correction and Veiling Glare Removal
Simplified optical systems often exhibit residual lens aberrations and Veiling Glare (VG), resulting in spatially varying blur and contrast reduction.Tensor-Engineered Van der Waals NbOCl2 Resonant Metasurface for Polarization-entangled Bell State Generation
Polarization-entangled photon pairs are essential resources for quantum information technologies, yet realizing compact sources with intrinsically controllable entanglement remains challenging.Generating Vector-Vortex $γ$ Photons by Nonlinear Compton Scattering
Vector-vortex photons, characterized by a nonseparable coupling between polarization and orbital angular momentum (OAM), offer opportunities for optical manipulation, quantum communication, nuclear…An Exact Polynomial Task-Risk Bridge for Time-Multiplexed Photonic Quantum Reservoirs
Time-multiplexed (TDM) photonic reservoirs are usually judged by their scores on a few datasets, which say little about a chip's overall performance, and designed by enumerating candidate circuits…Electron Density Measurements from Stark Broadened Emission in a Sodium Plasma Produced by Laser Resonance Saturation
Electron Stark broadening of the $4^2D$--$3^2P$ multiplet transition in a sodium plasma produced by laser resonance saturation has provided a means of undertaking the first spatial measurements of…Plasmon modes in tilted three-dimensional nodal-ring semimetals. I. $\mathcal{PT}$-symmetric nodal ring and its gapped cousin
We study collective charge excitations in three-dimensional $\mathcal{PT}$-symmetric nodal-ring semimetals (PTNRs) and their gapped counterparts (GNRs) in the presence of band tilt, together with…Multi-Aperture PPG with MAPIS: Spatial Optical and Temporal Coherence Fields
Conventional reflectance photoplethysmography (PPG) typically reduces tissue optical responses to one or a few detector channels.Democratizing Atomistic Simulation Workflows for the AI Era with the Quantum Accelerator
We present the Quantum Accelerator (QuAcc), an open-source workflow library for atomistic simulations with an emphasis on quantum-mechanical calculations.Vision-Language Agents for Active Perception in Optics Laboratories
Vision-language models (VLMs) are increasingly being used in scientific workflows, but their ability as agents to directly control laboratory experiments from visual feedback remains underexplored.Single-shot coherent process tomography and mid-infrared polarimetry with undetected photons
Measurements with undetected photons infer properties of a probe beam that is never detected, transferring mid-infrared information onto silicon-friendly wavelengths.Computational aberration-retrieval with entangled photons
Adaptive optics (AO) is central to high-resolution microscopy, yet conventional implementations often require repeated correction-and-measurement cycles whose number increases with aberration…
