Microwave to optical quantum transducer using mechanical resonators

研究人员迅速推动了建立量子处理器全球网络的努力，这是一种被称为“量子互联网”的范式，能够在遥远的量子计算机之间安全地传输信息。超导电路是芯片集成、快速处理和非经典状态合成的理想候选电路，这就是为什么它们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在光纤中使用光光子，由于其低损耗、大传输带宽和对热噪声的弹性，是唯一现实的候选电路。要实现和连接全功能量子处理器，需要将上述两种量子技术范式--计算和通信--整合到小型和大规模量子网络的联合系统中。为了实现远距离运行的网络，同时保持信号的量子特性，称为量子换能器的设备是必要的，以便在电信波长和各种节点的工作频率之间有效地传输或转换信息。在这个项目中，我们的目标是开发量子换能器，重点是利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联网量子器件。IST奥地利分校独特的制造设施使加州大学卡尔加里分校的团队能够更有效地对量子设备进行纳米加工。这将带来许多社会经济利益，包括研究影响加拿大人日常生活并对加拿大政府具有战略优先地位的革命性和根本性改进的通信/网络基础设施，以及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使用。

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.
