Inequalities and separations among assisted capacities of quantum channels
Charles H. Bennett, Igor Devetak, Peter W. Shor +1
We exhibit discrete memoryless quantum channels whose quantum capacity assisted by two-way classical communication, , exceeds their unassisted one-shot Holevo capacity .…
Universal quantum data compression via gentle tomography
Charles H. Bennett, Aram W. Harrow, Seth Lloyd
Quantum state tomography--the practice of estimating a quantum state by performing measurements on it--is useful in a variety of contexts. We introduce "gentle tomography" as a ver…
Improvements to time bracketed authentication
Charles H. Bennett
We describe a collection of techniques whereby audiovisual or other recordings of significant events can be made in a way that hinders falsification, pre-dating, or post-dating by…
Remote preparation of quantum states
Charles H. Bennett, Patrick Hayden, Debbie W. Leung +2
Remote state preparation is the variant of quantum state teleportation in which the sender knows the quantum state to be communicated. The original paper introducing teleportation…
Trust enhancement by multiple random beacons
Charles H. Bennett, John A. Smolin
Random beacons-information sources that broadcast a stream of random digits unknown by anyone beforehand-are useful for various cryptographic purposes. But such beacons can be easi…
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…
