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…
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…
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…
