Quiness: Hybrid Quantum Nano-Photonic Devices Based on Erbium Doped Crystals
Abstract
This research will enable on-chip optical quantum memories that operate in the telecom band, and quantum conversion between microwave photons and optical photons for optical communications with superconducting quantum machines. Efficient optical quantum memories at telecom wavelengths can be realized using silicon nano-photonic resonators that improve the optical spin pumping of Erbium Er3+ ions (coupled to the resonator). Single microwave photons could be coherently converted to single optical photons using Er ions coupled with high cooperativity to both optical and microwave resonators. Caltech expects to demonstrate memories with efficiencies up to 10% and storage times exceeding 1 microsecond with prospects for extending to millisecond.
