Quantum dual extended Hamming code immune to collective coherent errors
En-Jui Chang
Collective coherent (CC) errors are inevitable, as every physical qubit undergoes free evolution under its kinetic Hamiltonian. These errors can be more damaging than stochastic Pa…

High-rate extended binomial codes for multiqubit encoding
En-Jui Chang
We introduce a class of bosonic quantum error-correcting codes, termed \emph{extended binomial codes}, which generalize the structure of one-mode binomial codes by incorporating id…
