Researchers have driven rapidly surging efforts to build a global network of quantum processors, a paradigm known as the "Quantum Internet" which enables the secure transmission of information between distant quantum computers. Superconducting circuits are good candidates for on-chip integration, fast processing, and non-classical state synthesis, which is why they have become a major focus of industrial research As in conventional telecommunication networks, long-distance quantum communication requires the use of light optical photons in fibres are the only realistic candidates due to their low loss, large bandwidth of transmission, and resilience to thermal noise. Realising and connecting fully functional quantum processors requires incorporating the two above-mentioned quantum technology paradigms-computation and communication-in joint systems for small- and large-scale quantum networks. To realize a network operating over long distances while preserving the quantum nature of the signal, devices referred to as quantum transducers are necessary to efficiently transfer or transduce, the information between telecom wavelengths and the operating frequency of the various nodes. In this project, we are aiming to develop quantum transducers by focusing on converting microwave signals to optical using mechanical resonators and developing long distance quantum communication and networking quantum devices. The unique fabrication facility at IST Austria allows the UCalgary team to nanofabricate the quantum devices more efficiently. This will lead to numerous socio-economic benefits, including research into revolutionary and fundamentally improved communication/network infrastructure that impacts the daily life of Canadians and is of strategic priority to the Government of Canada, and through training of future leaders and highly qualified personnel (HQP) for employment by Canadian companies, governmental laboratories, Government of Canada departments, and academic institutions.

研究人员已经推动了建立全球量子处理器网络的快速激增的努力，这种范式被称为“量子互联网”，它能够在远程量子计算机之间安全传输信息。超导电路是片上集成、快速处理和非经典状态合成的良好候选者，这就是为什么它们已经成为工业研究的主要焦点。在传统的电信网络中，长距离量子通信需要使用光纤中的光子，由于其低损耗、大带宽的传输和对热噪声的弹性，光纤中的光子是唯一现实的候选者。实现和连接功能齐全的量子处理器需要将上述两种量子技术范式计算和通信结合到小型和大型量子网络的联合系统中。为了实现在长距离上操作的网络，同时保持信号的量子性质，被称为量子换能器的设备对于在电信波长和各个节点的操作频率之间有效地传送或传输信息是必要的。在这个项目中，我们的目标是开发量子换能器，重点是使用机械谐振器将微波信号转换为光学信号，并开发长距离量子通信和网络量子设备。IST Austria独特的制造设施使UCalgary团队能够更有效地纳米制造量子器件。这将带来许多社会经济效益，包括研究革命性的和根本性的改善通信/网络基础设施，影响加拿大人的日常生活，是加拿大政府的战略优先事项，并通过培训未来的领导人和高素质人员（HQP），供加拿大公司，政府实验室，加拿大政府部门和学术机构就业。
