Quantum error correction

If left uncorrected, control errors and decoherence would destroy any sufficiently large quantum computation. Therefore, any scalable implementation of quantum computers will have to use quantum error correction and fault tolerance. Our group has been working on quantum error correction, with topics including passive error correction, encodings of fermions in qubits and in fermions, high-rate quantum LDPC codes, error correction with continuous variables, and error correction on hyperbolic lattices.
