Towards fault-tolerant quantum computation: near term and the future

Abstract

Quantum error-correcting codes (QECCs) can eliminate the negative effects of quantum noise, the major obstacle to the execution of quantum algorithms on large-scale quantum computers. However, realizing practical quantum error correction (QEC) and fault-tolerant quantum computation (FTQC) requires resolving many challenges, both theoretical and practical. These challenges include tremendous resource overhead, low accuracy threshold, low connectivity between qubits, state leakage, et.al. In this talk, I will give a brief review of the development of the theory of fault-tolerant quantum computation and its recent developments on both theoretical and experimental sides.
