Feedforward suppression of readout-induced faults in quantum error correction

The authors propose reducing readout-induced faults in error correction by using an adaptive readout sequence conditioned on each check qubit's measurement result from the previous cycle. Simulations of Pauli errors with a low-density parity check code show improvements manifesting as a lower logical error rate and faster decoding.

Abstract

The authors propose reducing readout-induced faults in error correction by using an adaptive readout sequence conditioned on each check qubit's measurement result from the previous cycle. Simulations of Pauli errors with a low-density parity check code show improvements manifesting as a lower logical error rate and faster decoding.
