Discrete-variable assisted error correction of continuous-variable quantum information
Negin Razian, En-Jui Chang, Hoi-Kwan Lau
Robust continuous-variable (CV) quantum information processing requires correcting realistic errors in bosonic systems, but all existing schemes rely on auxiliary Gottesman-Kitaev-…
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…
High-Rate Amplitude-Damping Shor Codes with Immunity to Collective Coherent Errors
En-Jui Chang, Ching-Yi Lai
We introduce a family of high-rate amplitude-damping (AD) Shor Codes, designed to effectively correct AD errors while maintaining immunity to collective coherent (CC) errors. The p…
How to surpass no-go limits in Gaussian quantum error correction and entangled Gaussian state distillation?
En-Jui Chang, Ching-Yi Lai
Gaussian quantum information processing with continuous-variable (CV) quantum information carriers holds significant promise for applications in quantum communication and quantum i…
