Photonic Systolic Array for All‐Optical Matrix–Matrix Multiplication

open access: yesLaser &Photonics Reviews, EarlyView.
A photonic systolic array is introduced, offering extreme parallelism in matrix‐matrix multiplication based on the synchronized movement of optical pulses along a crossbar array. Optical pulses traveling in perpendicular directions meet at freeform‐designed multiply‐accumulate units, each tailored to generate two signals whose intensity difference ...

512‐Fold Rotational Super‐Resolution via Four‐Photon High‐Dimensional Structured Light

open access: yesLaser &Photonics Reviews, EarlyView.
A quantum rotation sensor that combines four photon states and high dimensional structured light ‐ characterized by a topological charge of 128 ‐ demonstrates a 512‐fold angular super‐resolution. ABSTRACT Structured light enhances quantum information processing by combining quantum states of light and shaped wavefronts.

Mid‐Infrared Quantum Scanning Microscopy via Visible Light Beyond Spatial Correlations

open access: yesLaser &Photonics Reviews, EarlyView.
This work introduces a raster‐scanning approach based on quantum imaging with undetected light (QIUL) that probes samples in the mid‐infrared (MIR) spectral range while performing detection in the visible domain. Unlike previous QIUL implementations, this technique operates independently of photon‐pair spatial correlations and relies solely on induced ...

A Network Centered on the Visual‐Motor Cortex Is Critically Involved in Postural Abnormality in Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Background Postural abnormality (PA) is a key motor symptom in Parkinson's disease (PD) that leads to disability and death. However, the pathophysiology underlying PA is still unknown. Objective The objective of this study was to explore the neural patterns behind PAs and measures toward functional restoration using repetitive transcranial ...
