Communication over proven-secure quantum channels is potentially one of the most wide-ranging applications of currently developed quantum technologies. It is generally envisioned that in future quantum networks, separated nodes containing stationary solid-state or atomic qubits are connected via the exchange of optical photons over large distances. In this work, we explore an intriguing alternative for quantum communication via all-microwave networks. To make this possible, we describe a general protocol for sending quantum states through thermal channels, even when the number of thermal photons in the channel is much larger than one. The protocol can be implemented with state-of-the-art superconducting circuits and enables the transfer of quantum states over distances of ~ 100 m via microwave transmission lines cooled to only T = 4K. This opens up completely new possibilities for quantum communication within and across buildings, and consequently, for the implementation of intra-city quantum networks based on microwave technology only. |

Dr. Ze-Liang Xiang received his Ph. D in theoretical physics from Fudan University in 2013. From 2010 to 2014, he performed graduated and postdoctoral research in RIKEN, Japan. From 2014 to present, he is working in Atominstitut of Vienna University of Technology as a Marie Sklodowska-Curie fellow of European Union. His research focuses on the theoretical modeling of quantum phenomena and on implementations of quantum computing and quantum simulation schemes in AMO, solid-state, and hybrid quantum system. |
