量子态读写过程中的碰撞退相干
Collisional decoherence during writing and reading quantum states
摘要：
碰撞，即使它们不限制存储在基态超精细相干存储器中的量子信息的寿命，当它们发生在写入和读取过程中时，可能严重限制量子存储器的保真度。这对在热蒸气电池中实现量子过程及其作为量子存储器的性能施加了限制。我们在实验中研究了这些碰撞的影响。
英文摘要：
Collisions, even though they do not limit the lifetime of quantum information stored in ground state hyperfine coherences, may severely limit the fidelity for quantum memory when they happen during the write and read process. This imposes restrictions on the implementation of quantum processes in thermal vapor cells and their performance as a quantum memory. We study the effect of these collisions in our experiment.
