Quantum devices are at the heart of quantum sensors and quantum computers, technologies poised to surpass the limits of what can be measured or computed with classical technologies. Devices for quantum sensing, considered one of the first applications of quantum computers, are already delivering unprecedented sensitivity, speed, and efficiency, in present-day technological applications. Improvements in quantum devices have driven recent advances in noisy intermediate scale quantum (NISQ) computers on the cusp of outperforming classical computers in real-world problems, and in the future will enable general purpose quantum computers that mitigate noise and tackle a much wider class of problems. Canada is in pole position to cement international leadership in the quantum technology revolution. So great are the potential capabilities of quantum technologies that this sector could have the same economic impact as the integrated circuit revolution and the internet and tele-communications revolution in the last half-century. This proposal is for the purchase of dedicated reactive ion etching fabrication equipment for research on superconducting quantum devices for quantum sensors and quantum computers. The first device to be investigated is being pursued in partnership with a world-leading quantum computing company (D-Wave Systems). The quantum device is a superconducting nonlinear inductor having properties that will enable more qubits to be integrated in commercial quantum computers, and will enable quantum computer architectural innovations that will increase the number of use-cases for their quantum computer. The second device is an integrated single photon detector for integrated (on-chip) photonics with near-unity efficiency over a broad range of operating wavelengths, for secure quantum communication (quantum key distribution), for purely photonics-based quantum computers (Xanadu, PsiQuantum), and for spin-photonic quantum computing (Si donors or diamond NV). The third device is an ultra-miniaturized integrated NbTiN and TiN superconducting microwave resonator. The purpose of this device is to simplify the coupling and readout of high performance hole spin qubits, for general purpose quantum computers. These silicon-based platforms are poised to leverage the capabilities of modern foundries, greatly improving the prospects for commercial quantum sensors and large-scale UQCs that are tolerant to errors.

量子器件是量子传感器和量子计算机的核心，这些技术有望超越经典技术可以测量或计算的极限。量子传感设备被认为是量子计算机的首批应用之一，在当今的技术应用中已经提供了前所未有的灵敏度，速度和效率。量子器件的改进推动了噪声中间尺度量子计算机（NISQ）的最新进展，使其在现实世界问题中的表现优于经典计算机，并且在未来将使通用量子计算机能够减轻噪声并解决更广泛的问题。 加拿大在巩固量子技术革命的国际领导地位方面处于领先地位。量子技术的潜在能力如此巨大，以至于这一领域可能会产生与过去半个世纪的集成电路革命以及互联网和电信革命相同的经济影响。 本提案用于购买专用反应离子蚀刻制造设备，用于研究用于量子传感器和量子计算机的超导量子器件。第一个被研究的设备正在与世界领先的量子计算公司（D-Wave Systems）合作开发。量子器件是一种超导非线性电感器，其特性将使更多的量子比特能够集成到商用量子计算机中，并将实现量子计算机架构创新，这将增加其量子计算机的用例数量。第二个器件是集成单光子探测器，用于集成（片上）光子学，在宽范围的工作波长上具有接近1的效率，用于安全量子通信（量子密钥分发），用于纯光子学量子计算机（Xanadu，PsiQuantum），以及用于自旋光子量子计算（Si施主或金刚石NV）。第三个器件是超小型集成NbTiN和TiN超导微波谐振器。该器件的目的是简化高性能空穴自旋量子比特的耦合和读出，用于通用量子计算机。这些基于硅的平台有望利用现代代工厂的能力，大大改善商用量子传感器和大规模UQC的前景。
