Perfect initialization of a quantum computer of neutral atoms in an optical lattice of large lattice constant
J. Vala, A. V. Thapliyal, S. Myrgren +3
We propose a scheme for the initialization of a quantum computer based on neutral atoms trapped in an optical lattice with large lattice constant. Our focus is the development of a…
Entanglement-assisted capacity of a quantum channel and the reverse Shannon theorem
Charles H. Bennett, Peter W. Shor, John A. Smolin +1
The entanglement-assisted classical capacity of a noisy quantum channel is the amount of information per channel use that can be sent over the channel in the limit of many uses of…
Superactivation of Bound Entanglement
Peter W. Shor, John A. Smolin, Ashish V. Thapliyal
We show that, in a multi-party setting, two non-distillable (bound-entangled) states tensored together can make a distillable state. This is an example of true superadditivity of d…
Rank Two Bipartite Bound Entangled States Do Not Exist
Pawel Horodecki, John A. Smolin, Barbara M. Terhal +1
We explore the relation between the rank of a bipartite density matrix and the existence of bound entanglement. We show a relation between the rank, marginal ranks, and distillabil…
Entanglement of Assistance
David P. DiVincenzo, Christopher A. Fuchs, Hideo Mabuchi +3
The newfound importance of ``entanglement as a resource'' in quantum computation and quantum communication compels us to quantify it in as many distinct ways as possible. Here we e…
