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 observable correlation for a bipartite quantum system
Michael J. W. Hall, Erika Andersson, Thomas Brougham
The maximum observable correlation between the two components of a bipartite quantum system is a property of the joint density operator, and is achieved by making particular measur…
Operational approach to the Uhlmann holonomy
Johan Aberg, David Kult, Erik Sjöqvist +1
We suggest a physical interpretation of the Uhlmann amplitude of a density operator. Given this interpretation we propose an operational approach to obtain the Uhlmann condition fo…
Retrodictive fidelities for pure state postselectors
John Jeffers
Two measures of fidelity are proposed for postselecting devices, the retrodictive conditional probability that the state in the measurement arm is the one indicated by the detector…
Scalable Error Correction in Distributed Ion Trap Computers
Daniel K. L. Oi, Simon J. Devitt, Lloyd C. L. Hollenberg
A major challenge for quantum computation in ion trap systems is scalable integration of error correction and fault tolerance. We analyze a distributed architecture with rapid high…
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…
Experimentally realizable quantum comparison of coherent states and its applications
Erika Andersson, Marcos Curty, Igor Jex
When comparing quantum states to each other, it is possible to obtain an unambiguous answer, indicating that the states are definitely different, already after a single measurement…
