Long-distance dynamical entanglement transfer via a chiral waveguide

2019 · arXiv (Cornell University)

Quantum networks provide a prominent platform for realizing quantum information processing and quantum communication, with entanglement being a key resource in such applications. Here, we describe the dissipative transport protocol for entangled states, where entanglement …

A VCSEL-based Optical Ising Computer with Parallel Feedback System for Large-Scale Optimization

2025

We propose an optical architecture utilizing injection-locked Vertical Cavity Surface Emitting Lasers (VCSELs) with parallel feedback allowing all-to-all connections without electrical bottleneck. Experimental realization of single bit switching is demonstrated as a proof-of-concept.
