Abstract given by the source: Quantum computing promises solutions to important societal problems involving chemistry, medicine, or logistics, and new applications such as a quantum internet. A quantum computer requires hundreds of identical quantum memories with switchable interconnections. However, quantum memories and their interconnecting circuits are very sensitive to their geometry, and even with the most advanced nanofabrication, no technology has yet achieved a large enough number of interconnected qubits to outperform classical computers.In this project, we use on-chip micromechanical (MEMS) tuning to tackle the scalability limitations of quantum computing. During the first year at MIT, we will develop a material platform that combines quantum memories based on diamond defects with quantum-compatible MEMS actuators and photonic integrated circuits (PICs). In year 2, we will demonstrate 1) spectral alignment of PIC-coupled quantum memories using MEMS-induced strain, and 2) MEMS-reconfigurable PICs. By the end of year 2, we will integrate these components into a quantum processing module, inherently scalable due to the use of MEMS. By year 3, we will demonstrate the first photonic quantum processor featuring 10 quantum memories, and scalable to thousands. This technology will open new avenues for quantum information processing, and bring us closer to large-scale quantum computing.
