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…
Gravitational Effects in Quantum Mechanics
A. D. K. Plato, C. N. Hughes, M. S. Kim
To date, both quantum theory, and Einstein's theory of general relativity have passed every experimental test in their respective regimes. Nevertheless, almost since their inceptio…
Universal state orthogonalizer and qubit generator
Antonio S. Coelho, Luca S. Costanzo, Alessandro Zavatta +3
The superposition principle is at the heart of quantum mechanics and at the root of many paradoxes arising when trying to extend its predictions to our everyday world. Schroedinger…
Quantum non-Gaussianity witnesses in the phase space
Catherine Hughes, Marco G. Genoni, Tommaso Tufarelli +2
We address detection of quantum non-Gaussian states, i.e. nonclassical states that cannot be expressed as a convex mixture of Gaussian states, and present a method to derive a new…
