We report long coherence times (up to 300 ms) for near-surface bismuth donor electron spins in silicon coupled to a superconducting microresonator, biased at a clock transition. This enables us to demonstrate the partial absorption of a train of weak microwave fields in the spin ensemble, their storage for 100 ms, and their retrieval, using a Hahn-echo-like protocol. Phase coherence and quantum statistics are preserved in the storage.

电子自旋中超过100 ms的量子微波场的多模存储

我们报道了硅的近表面铋供体电子自旋很长的相干时间（最高300毫秒），硅耦合到超导微谐振器，并在时钟转变时产生偏压。这使我们能够使用类似Hahn-echo的协议演示自旋系综中一系列弱微波场的部分吸收，它们的存储100 ms以及它们的恢复。相干和量子统计信息保存在存储器中。
