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 …

Code regarding the article "Reservoir computing with all-optical non-fading memory in a self-pulsing microresonator network"

2024 · arXiv (Cornell University)

Photonic neuromorphic computing may offer promising applications for a broad range of photonic sensors, including optical fiber sensors, to enhance their functionality while avoiding loss of information, energy consumption, and latency due to optical-electrical conversion. …

Photonic Spiking Reservoir Computing Based on a Single Passive Silicon Microring and Time-Wavelength Multiplexing

2025

Spiking artificial neural networks leverage both analog (spike firing time) and digital (spike or quiescent state) processing modalities to efficiently process information through spike sparsity and are widely explored in electronic hardware [1]. In this …

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 …
