Deterministic Twirling with Low Resources
David Jakob Stonner, Jaroslav Kysela, Graeme Weir +3
Twirling operations, which average a quantum state with respect to a unitary subgroup, have become a frequently-employed tool in quantum information processing. We investigate the…
Optimal measurement strategies for the trine states with arbitrary prior probabilities
Graeme Weir, Catherine Hughes, Stephen M. Barnett +1
We investigate the optimal measurement strategy for state discrimination of the trine ensemble of qubit states prepared with arbitrary prior probabilities. Our approach generates t…
Optimal sequential measurements for bi-partite state discrimination
Sarah Croke, Stephen M. Barnett, Graeme Weir
State discrimination is a useful test problem with which to clarify the power and limitations of different classes of measurement. We consider the problem of discriminating between…
Optimal discrimination of single-qubit mixed states
Graeme Weir, Stephen M. Barnett, Sarah Croke
We consider the problem of minimum-error quantum state discrimination for single-qubit mixed states. We present a method which uses the Helstrom conditions constructively and analy…
