Superefficient cascade multiresonator quantum memory
arXiv:1809.08759 · doi:10.1088/1612-202X/aae782
Abstract
We propose a cascade scheme of a superefficient broadband quantum memory consisting of four high-Q ring resonators forming a controllable frequency comb and interacting with long-lived spin systems and with a common waveguide. Using the transfer function giving extended matching conditions, the optimization of all spectroscopic parameters of the system for quantum memory in the resonator is carried out. It was shown that our quantum memory scheme does not impose large restrictions on the parameters of losses in resonators and allows to achieve super high efficiency 99.99 % in a wide frequency range.
