Vacuum Friction
Stephen M. Barnett, Matthias Sonnleitner
We know that in empty space there is no preferred state of rest. This is true both in special relativity but also in Newtonian mechanics with its associated Galilean relativity. It…
Journeys from Quantum Optics to Quantum Technology
Stephen M. Barnett, Almut Beige, Artur Ekert +17
Sir Peter Knight is a pioneer in quantum optics which has now grown to an important branch of modern physics to study the foundations and applications of quantum physics. He is lea…
Sequential measurements: Busch-Gleason theorem and its applications
Kieran Flatt, Stephen M. Barnett, Sarah Croke
Probabilities enter quantum mechanics via Born's rule, the uniqueness of which was proven by Gleason. Busch subsequently relaxed the assumptions of this proof, expanding its domain…
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…
The Roentgen interaction and forces on dipoles in time-modulated optical fields
Matthias Sonnleitner, Stephen M. Barnett
The Roentgen term is an often neglected contribution to the interaction between an atom and an electromagnetic field in the electric dipole approximation. In this work we discuss h…
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…
