Classical simulation of noninteracting-fermion quantum circuits
Barbara M. Terhal, David P. DiVincenzo
We show that a class of quantum computations that was recently shown to be efficiently simulatable on a classical computer by Valiant corresponds to a physical model of noninteract…
Classical capacity of a noiseless quantum channel assisted by noisy entanglement
Michal Horodecki, Pawel Horodecki, Ryszard Horodecki +2
We derive the general formula for the capacity of a noiseless quantum channel assisted by an arbitrary amount of noisy entanglement. In this capacity formula, the ratio of the quan…
Quantum Data Hiding
David P. DiVincenzo, Debbie W. Leung, Barbara M. Terhal
We expand on our work on Quantum Data Hiding -- hiding classical data among parties who are restricted to performing only local quantum operations and classical communication (LOCC…
Detecting Quantum Entanglement
Barbara M. Terhal
We review the criteria for separability and quantum entanglement, both in a bipartite as well as a multipartite setting. We discuss Bell inequalities, entanglement witnesses, entro…
