Spin-Echo Silencing Using a Current-Biased Frequency-Tunable Resonator
Spin-Echo Silencing Using a Current-Biased Frequency-Tunable Resonator
The ability to control microwave emission from a spin ensemble is a requirement of several quantum memory protocols. Here, we demonstrate such ability by using a resonator whose frequency can be rapidly tuned with a bias current. We store excitations in an ensemble of rare-earth ions and suppress on demand …
