Quantum Information as a Measure of Multipartite Correlation
Simon James Daniel Phoenix
The mutual information has been successfully used as a measure of correlation strength between quantum systems, especially for bipartite systems. Here we examine the use of this me…
A Note on the Entropy of Entanglement and Entanglement Swapping Bounds
Simon James Daniel Phoenix
Using the information content of correlations between multipartite systems, together with the notion of partitioning, we show that some general results about the evolution of corre…
Asynchronous QKD on a Relay Network
S. M. Barnett, S. J. D. Phoenix
We show how QKD on a multi-user, multi-path, network can be used to establish a key between any two end users in an asynchronous fashion using the technique of bit-transport. By a…
Detecting an Eavesdropper in QKD Without Public Bit Comparison
Stephen M. Barnett, Simon J. D. Phoenix
We present a method for determining the presence of an eavesdropper in QKD systems without using any public bit comparison. Alice and Bob use a duplex QKD channel and the bit trans…
Playing Games with Quantum Mechanics
Simon J. D. Phoenix, Faisal Shah Khan
We present a perspective on quantum games that focuses on the physical aspects of the quantities that are used to implement a game. If a game is to be played, it has to be played w…
Gaming the Quantum
Faisal Shah Khan, Simon J. D. Phoenix
In the time since a merger of quantum mechanics and game theory was proposed formally in 1999, the two distinct perspectives apparent in this merger of applying quantum mechanics t…
