论文摘要
从旋转集合中控制微波排放的能力是几种量子存储协议的要求。在这里，我们通过使用谐振器来证明这种能力，该谐振器可以用偏置电流快速调节频率。我们通过两种方法将激发量存储在稀土离子的集合中，并抑制单调的回声发射（“回声沉默”）：1）在自旋旋转过程中解散谐振器，以及2）对偏置本身产生的磁场梯度对磁场梯度产生。我们还表明，在沉默过程中保留了自旋连贯性。
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.
