Entanglement of assistance and multipartite state distillation
John A. Smolin, Frank Verstraete, Andreas Winter
We find that the asymptotic entanglement of assistance of a general bipartite mixed state is equal to the smaller of its two local entropies. Our protocol gives rise to the asympto…
The Continuous Variable Quantum Teleportation Controversy
John A. Smolin
I argue that the objections by Rudolph and Sanders \cite{RS} to performing continuous variable quantum teleportation experiments using lasers, as well as the various rebuttals to t…
Security Trade-offs in Ancilla-Free Quantum Bit Commitment in the Presence of Superselection Rules
D. P. DiVincenzo, J. A. Smolin, B. M. Terhal
Security trade-offs have been established for one-way bit commitment in quant-ph/0106019. We study this trade-off in two superselection settings. We show that for an `abelian' supe…
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 .…
Can Quantum Cryptography Imply Quantum Mechanics?
John A. Smolin
It has been suggested that the ability of quantum mechanics to allow secure distribution of secret key together with its inability to allow bit commitment or communicate superlumin…
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…
