Secret Keys Assisted Private Classical Communication Capacity over Quantum Channels (2008)
Hsieh, Min-Hsiu, Luo, Zhicheng, Brun, Todd
We prove a regularized formula for the secret key-assisted capacity region of a quantum channel for transmitting private classical information. This result parallels the work of Devetak on...
Continuous monitoring can improve indistinguishability of a single-photon source (2008)
Raghunathan, Shesha, Brun, Todd
A new engineering technique using continuous quantum measurement in conjunction with feed-forward is proposed to improve indistinguishability of a single-photon source. The technique involves...
General entanglement-assisted quantum error-correcting codes (2007)
Hsieh, Min-Hsiu, Devetak, Igor, Brun, Todd
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 possible to construct an...
Correcting Quantum Errors with Entanglement (2006)
Brun, Todd, Devetak, Igor, Hsieh, Min-Hsiu
We show how entanglement shared between encoder and decoder can simplify the theory of quantum error correction. The entanglement-assisted quantum codes we describe do not require the dual-containing...
Catalytic quantum error correction (2006)
Brun, Todd, Devetak, Igor, Hsieh, Min-Hsiu
We develop the theory of entanglement-assisted quantum error correcting (EAQEC) codes, a generalization of the stabilizer formalism to the setting in which the sender and receiver have access to...
Book, David L., Brun, Todd, Scotgt, Robert J.
The NRL Plasma Formulary is a collection of formulas and reference data in a handy pocketsized booklet. This report contains some sixty pages of text, tables, and displayed equations, together with...
