Current Research

  • My group studies the physical aspects of quantum information and computation, with a focus on quantum error correction and fault tolerance, to mitigate the effects of noise in quantum computing devices. Our current interest is on bringing quantum error correction and fault-tolerant computing ideas closer to experimental realisation.
