Quantum computers have the potential to solve specific algorithms allowing us to better simulate complex systems at increased speed and accuracy compared with classical binary computing. Ultimately, there needs to be a connection to the outside 'classical' world or a means to interface quantum computers for networking functionality. Quantum processors based on superconducting circuitry must be cooled to cryogenic temperatures, isolating qubits in a controlled quantum state, and therefore posses a major technical challenge for establishing a physical interconnect. The solution proposed here, it to implement an optical interface that would allow data transfer from a low-temperature environment with minimal thermal load; additionally, photonic circuits lend themselves to high-speed modulation with low energy cost per bit. The outline of this research project is to design, fabricate and test an optical interface for superconducting quantum processors. The student will have an exciting opportunity to work closely with the industry sponsor SEEQC, who are working to deliver a commercially scalable and cost-effective digital quantum computing platform for global businesses.

量子计算机具有求解特定算法的潜力，使我们能够更好地模拟与经典二进制计算相比，以提高速度和准确性的复杂系统。最终，需要与外部“古典”世界或连接量子计算机进行网络功能的方式有联系。基于超导电路的量子处理器必须冷却至低温温度，在受控量子状态下隔离量子位，因此对建立物理互连的量子构成了重大的技术挑战。这里提出的解决方案是实现光学接口，该光学接口将允许从低温环境中传输数据，并以最小的热负载。此外，光子电路将自己用于高速调制，每位能量成本低。该研究项目的轮廓是设计，制造和测试用于超导量子处理器的光学接口。该学生将有一个激动人心的机会与行业发起人SeeQC紧密合作，后者正在为全球企业提供商业上可扩展且具有成本效益的数字量子计算平台。
