Quantum Key Distribution Highly Sensitive to Eavesdropping
Stephen Brierley
We introduce a new quantum key distribution protocol that uses d-level quantum systems to encode an alphabet with c letters. It has the property that the error rate introduced by a…

Maximal Sets of Mutually Unbiased Quantum States in Dimension Six
Stephen Brierley, Stefan Weigert
We study sets of pure states in a Hilbert space of dimension d which are mutually unbiased (MU), that is, the squares of the moduli of their scalar products are equal to zero, one,…

On maximal entanglement between two pairs in four-qubit pure states
Stephen Brierley, Atsushi Higuchi
We show that the state with the highest known average two-particle von Neumann entanglement entropy proposed by Sudbery and one of the authors gives a local maximum of this entropy…
