On improving single photon sources via linear optics and photodetection

Dominic W. Berry, Stefan Scheel, Barry C. Sanders +1

In practice, single photons are generated as a mixture of vacuum with a single photon with weights 1-p and p, respectively; here we are concerned with increasing p by directing mul…

Direct observation of non-classical photon statistics in parametric downconversion

Edo Waks, Eleni Diamanti, Barry C. Sanders +2

We employ a high quantum efficiency photon number counter to determine the photon number distribution of the output field from a parametric downconverter. The raw photocount data d…

Numerical Analysis of the Capacities for Two-Qubit Unitary Operations

Dominic W. Berry, Barry C. Sanders

We present numerical results on the capacities of two-qubit unitary operations for creating entanglement and increasing the Holevo information of an ensemble. In all cases tested,…

Continuous-time quantum walks on the symmetric group

Heath Gerhardt, John Watrous

In this paper we study continuous-time quantum walks on Cayley graphs of the symmetric group, and prove various facts concerning such walks that demonstrate significant differences…

Bounds on general entropy measures

Dominic W. Berry, Barry C. Sanders

We show how to determine the maximum and minimum possible values of one measure of entropy for a given value of another measure of entropy. These maximum and minimum values are obt…
