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.

传播量子微波的量子隐形传态

已经提出并成功地实现了传播量子微波的产生纠缠，从而为实现量子通信通道建立了有希望的平台。但是，仍然缺少在微波状态下用光子进行量子隐形传态的方法。同时，该领域的最新进展表明，该关键协议可以通过当前技术实现，这将为扩大微波量子通信领域铺平道路。在这里，我们讨论了在现实情况下有损耗的情况下实现微波量子隐形传态的可行性。此外，我们提出了如何在不使用光检测的情况下在微波范围内实现量子中继器，这是实现长距离纠缠分布的关键前提。
