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…

All Mutually Unbiased Bases in Dimensions Two to Five
Stephen Brierley, Stefan Weigert, Ingemar Bengtsson
All complex Hadamard matrices in dimensions two to five are known. We use this fact to derive all inequivalent sets of mutually unbiased (MU) bases in low dimensions. We find a thr…

Constructing Mutually Unbiased Bases in Dimension Six
Stephen Brierley, Stefan Weigert
The density matrix of a qudit may be reconstructed with optimal efficiency if the expectation values of a specific set of observables are known. In dimension six, the required obse…
