Quantum Formulation of Fractional Orbital Angular Momentum
J. B. Goette, S. Franke-Arnold, R. Zambrini +1
The quantum theory of rotation angles (S. M. Barnett and D. T. Pegg, Phys. Rev. A, 41, 3427-3425 (1990)) is generalised to non-integer values of the orbital angular momentum. This…
Experimental Realization of Maximum Confidence State Discrimination for the Extraction of Quantum Information
Peter J. Mosley, Sarah Croke, Ian A. Walmsley +1
We present the first experimental demonstration of the maximum confidence measurement strategy for quantum state discrimination. Applying this strategy to an arbitrary set of state…
Maximum Confidence Quantum Measurements
Sarah Croke, Erika Andersson, Stephen M. Barnett +2
We consider the problem of discriminating between states of a specified set with maximum confidence. For a set of linearly independent states unambiguous discrimination is possible…
Measurement master equation
James D. Cresser, Stephen M. Barnett, John Jeffers +1
We derive a master equation describing the evolution of a quantum system subjected to a sequence of observations. These measurements occur randomly at a given rate and can be of a…
Cloning and Joint Measurements of Incompatible Components of Spin
Thomas Brougham, Erika Andersson, Stephen M. Barnett
A joint measurement of two observables is a {\it simultaneous} measurement of both quantities upon the {\it same} quantum system. When two quantum-mechanical observables do not com…
