Proof of a positive coherent-error threshold for topological quantum codes
Shiro Tamiya, Masato Koashi
Threshold analyses of quantum error-correcting codes are well established for stochastic error models, in which errors occur randomly with given probabilities. However, errors in a…

Polylog-time- and constant-space-overhead fault-tolerant quantum computation with quantum low-density parity-check codes
Shiro Tamiya, Masato Koashi, Hayata Yamasaki
A major challenge in fault-tolerant quantum computation (FTQC) is to reduce both space overhead -- the large number of physical qubits per logical qubit -- and time overhead -- the…
