Tracking quantum error correction [PDF]
Physical Review A, 2018 To implement fault-tolerant quantum computation with continuous variables, the Gottesman--Kitaev--Preskill (GKP) qubit has been recognized as an important technological element. We have proposed a method to reduce the required squeezing level to realize large scale quantum computation with the GKP qubit [Phys. Rev. X.

The Qubit Fidelity Under Different Error Mechanisms Based on Error Correction Threshold
Frontiers in Physics, 2022 Quantum error correction is a crucial step to realize large-scale universal quantum computing, and the condition for realizing quantum error correction is that the error probability of each operation step must below some threshold. This requires that the
