Talk Title
Modular Quantum Computing
Abstract
Connecting smaller quantum processors offers a path toward scalable quantum computing, but requires efficient ways to divide computations, communicate between modules, and protect against errors. In this talk, I will discuss our work on these challenges, beginning with circuit cutting, which reconstructs larger computations from smaller experiments, and its applications to optimization and error mitigation. I will then explain how the sampling cost of circuit cutting motivates quantum links and examine the conditions under which these links can offer an advantage. Finally, I will present approaches to distributed quantum error correction that concentrate protection at noisy interfaces and limit the spread of connection faults. These examples highlight how algorithms, quantum communication, and error correction can be designed together to make small quantum processors work as a larger system.
