Entanglement-Assisted Quantum Error-Correcting Codes
Todd Brun, Min-Hsiu Hsieh
We provide a self-contained introduction for entanglement-assisted quantum error-correcting codes in this book chapter.
Quantum Reverse Shannon Theorem
Charles H. Bennett, Igor Devetak, Aram W. Harrow +2
Dual to the usual noisy channel coding problem, where a noisy (classical or quantum) channel is used to simulate a noiseless one, reverse Shannon theorems concern the use of noisel…
Entanglement-Assisted Quantum Quasi-Cyclic Low-Density Parity-Check Codes
Min-Hsiu Hsieh, Todd A. Brun, Igor Devetak
We investigate the construction of quantum low-density parity-check (LDPC) codes from classical quasi-cyclic (QC) LDPC codes with girth greater than or equal to 6. We have shown th…
General entanglement-assisted quantum error-correcting codes
Min-Hsiu Hsieh, Igor Devetak, Todd Brun
Entanglement-assisted quantum error-correcting codes (EAQECCs) make use of pre-existing entanglement between the sender and receiver to boost the rate of transmission. It is possib…
Optimal quantum source coding with quantum information at the encoder and decoder
Jon Yard, Igor Devetak
Consider many instances of an arbitrary quadripartite pure state of four quantum systems ABCD. Alice holds the AC part of each state, Bob holds B, while D represents all other part…
Local purity distillation with bounded classical communication
Hari Krovi, Igor Devetak
Local pure states are an important resource for quantum computing. The problem of distilling local pure states from mixed ones can be cast in an information theoretic paradigm. The…
