Theoretical Research on Quantum Computing
Quantum computing is a budding technology that will do computations that can’t be done in classical supercomputers (quantum supremacy). It will revolutionize the scientific research and the society. While still in its early stage, commercial quantum computers are already emerging. Here are some of my research directions.
