To implement fault-tolerant quantum computation with continuous variables, continuous variables need to be digitized using an appropriate code such as the Gottesman--Kitaev--Preskill (GKP) qubit. We have developed a method to alleviate the required squeezing level to realize fault-tolerant quantum computation with the GKP qubit [K. Fukui, A. Tomita, A. Okamoto, and K. Fujii, Phys. Rev. X {\bf 8}, 021054 (2018)]. In the previous work, the required squeezing level can be reduced to less than 10…
