Quantum states generation and manipulation in a programmable silicon-photonic four-qubit system with high-fidelity and purity

2024 · APL Photonics

We present a programmable silicon photonic four-qubit integrated circuit for the generation and manipulation of diverse quantum states. The silicon photonic chip integrates photon-pair sources, pump-reducing filters, wavelength-division-multiplexing filters, Mach–Zehnder interferometer switches, and single-qubit arbitrary …

Mémristors quantiques photoniques intégrés couplés utilisant une source de photons uniques constituée d'un centre de couleur

2026 · HAL (Le Centre pour la Communication Scientifique Directe)

<div> Photonic quantum memristors provide a measurement-induced route to nonlinear and history-dependent quantum dynamics. Experimental demonstrations have so far focused on isolated devices or simple cascaded devices configurations. Here, we experimentally realize and characterize a …
