Quantum Devices to Improve the Scalability of Commercial Annealing Quantum Computers

通过利用经典计算机中不存在的量子物理的不寻常特性，量子计算机准备在优化和材料设计等领域解决具有社会重要性的计算问题，这些问题在经典计算机上是不可能或非常困难的。随着许多科学障碍的克服，中等规模的量子计算机已经在一些领先的公司中作为商业产品出现，并且这种规模的工程量子系统的挑战已经成为前景。该提案旨在通过实验研究非线性量子设备，以期帮助D-Wave解决其核心商业活动的基础和工程挑战：制造基于量子退火的量子计算机，速度更快，可以解决更大的问题，并且可以解决更广泛的问题。该提案包括三个阶段，器件设计，使用工业兼容的平面工艺进行微制造，以及在低噪声低温环境中进行测量。该项目的成功将使D-Wave在竞争对手中获得竞争优势，为D-Wave和1QBit等密切相关的公司在加拿大量子领域创造更多就业机会，使加拿大更好地获得量子计算机技术的经济效益。

By exploiting the unusual properties of quantum physics not present in classical computers, quantum computers are poised to tackle computational problems of societal importance in areas like optimization and materials design that are impossible, or very difficult, on classical computers. With many scientific hurdles now overcome, intermediate-scale quantum computers have emerged as a commercial product at a few leading companies, and the challenges of engineering quantum systems at this scale have come to the foreground. This proposal aims to experimentally investigate non-linear quantum devices anticipated to assist D-Wave in the fundamental and engineering challenges of their core commercial activity: making quantum annealing based quantum computers that are faster, can solver larger problems, and can tackle a wider variety of problems. The proposal encompasses three stages, device design, micro-fabrication using an industry-compatible planar process, and measurement in low-noise cryogenic environment. Success of the project will give D-Wave a competitive advantage over competitors, create more jobs in the Canadian quantum sector at D-Wave and closely related companies like 1QBit, better positioning Canada to reap the economic benefits of quantum computer technology.
