控制自旋系综微波发射的能力是许多量子存储协议的要求。在这里，我们通过使用一个谐振器来证明这种能力，该谐振器的频率可以用偏置电流快速调谐。我们将激发存储在稀土离子系综中，并通过两种方法根据需要抑制回波发射（“回波沉默”）：(1)在自旋重相和(2)使自旋受到偏置电流本身产生的磁场梯度的影响。我们还表明，自旋相干性在沉默期间得以保留。
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 the echo emission ("echo silencing") by two methods: (1) detuning the resonator during the spin rephasing, and (2) subjecting spins to magnetic field gradients generated by the bias current itself. We also show that spin coherence is preserved during silencing.
