Fault-tolerant quantum error correction using error weight parities
Theerapat Tansuwannont, Debbie Leung · Physical Review A · 2021
Current fault-tolerant quantum computation protocols require the preparation of a large number of auxiliary qubits. In contrast, the ``weight parity error correction'' introduced here is a remarkably qubit-efficient technique for correcting even high-weight errors in some stabilizer codes, provided that the weight parity is known.
