The physics of no-bit-commitment : Generalized quantum non-locality versus oblivious transfer
Tony Short, Nicolas Gisin, Sandu Popescu
We show here that the recent work of Wolf and Wullschleger (quant-ph/0502030) on oblivious transfer apparently opens the possibility that non-local correlations which are stronger…
Practical Implementations of Twirl Operations
M. S. Anwar, L. Xiao, A. J. Short +4
Twirl operations, which convert impure singlet states into Werner states, play an important role in many schemes for entanglement purification. In this paper we describe strategies…
Fidelity of Single Qubit Maps
M. D. Bowdrey, D. K. L. Oi, A. J. Short +2
We describe a simple way of characterizing the average fidelity between a unitary (or anti-unitary) operator and a general operation on a single qubit, which only involves calculat…
Fidelity of Single Qubit Maps
M. D. Bowdrey, D. K. L. Oi, A. J. Short +1
We give a simple way of characterising the average fidelity between a unitary and a general operation on a single qubit which only involves calculating the fidelities for a few pur…
Comment on "Experimental realization of Popper's experiment: Violation of the uncertainty principle?"
A. J. Short
Application of the uncertainty principle to conditional measurements is investigated, and found to be valid for measurements on separated sub-systems. In light of this, an apparent…
