LDPC Quantum Codes: Recent Developments, Challenges and Opportunities
Nikolas Breuckmann, University College London
Quantum error correction is an indispensable ingredient for scalable quantum computing. We discuss a particular class of quantum codes called "quantum low-density parity-check (LDPC) codes." The codes we discuss are alternatives to the surface code, which is currently the leading candidate to implement quantum fault tolerance. We discuss the zoo of quantum LDPC codes and discuss their potential for making quantum computers robust with regard to noise.
