Optimal Remote State Preparation
Dominic W. Berry, Barry C. Sanders
We prove that it is possible to remotely prepare an ensemble of non-commuting mixed states using communication equal to the Holevo information for this ensemble. This remote prepar…
Relation between classical communication capacity and entanglement capability for two-qubit unitary operations
Dominic W. Berry, Barry C. Sanders
Two-qubit operations may be characterized by their capacities for communication, both with and without free entanglement, and their capacity for creating entanglement. We establish…
Relations for classical communication capacity and entanglement capability of two-qubit operations
Dominic W. Berry, Barry C. Sanders
Bipartite operations underpin both classical communication and entanglement generation. Using a superposition of classical messages, we show that the capacity of a two-qubit operat…
Near-optimal two-mode spin squeezing via feedback
Dominic W. Berry, Barry C. Sanders
We propose a feedback scheme for the production of two-mode spin squeezing. We determine a general expression for the optimal feedback, which is also applicable to the case of sing…
Adaptive Phase Measurements
Dominic Berry
In this thesis I consider the general problem of how to make the best possible phase measurements using feedback. Both the optimum input state and optimum feedback are considered f…
