已经提出并成功实现了量子微波的纠缠，从而为实现量子通信信道建立了一个有前途的平台。然而，在微波区实现光子量子隐形传态仍然是缺席。与此同时，该领域的最新进展表明，这种关键协议在当前技术下是可行的，这将为推动微波量子通信领域的发展铺平道路。在这里，我们讨论了一个可能的实现微波量子隐形传态在一个现实的情况下的损失的可行性。此外，我们提出了如何实现量子中继器在微波制度，而不使用光电探测，实现长距离纠缠分布的关键先决条件。
Propagating quantum microwaves have been proposed and successfully implemented to generate entanglement, thereby establishing a promising platform for the realisation of a quantum communication channel. However, the implementation of quantum teleportation with photons in the microwave regime is still absent. At the same time, recent developments in the field show that this key protocol could be feasible with current technology, which would pave the way to boost the field of microwave quantum communication. Here, we discuss the feasibility of a possible implementation of microwave quantum teleportation in a realistic scenario with losses. Furthermore, we propose how to implement quantum repeaters in the microwave regime without using photodetection, a key prerequisite to achieve long distance entanglement distribution.
