Streaming universal distortion-free entanglement concentration
Robin Blume-Kohout, Sarah Croke, Daniel Gottesman
This paper presents a streaming (sequential) protocol for universal entanglement concentration at the Shannon bound. Alice and Bob begin with N identical (but unknown) two-qubit pu…
Noiseless linear amplification via weak measurements
David Menzies, Sarah Croke
We discuss the recently introduced concept of non-deterministic noiseless linear amplification, demonstrating that such an operation can only be performed perfectly with vanishing…
Quantum state discrimination
Stephen M. Barnett, Sarah Croke
It is a fundamental consequence of the superposition principle for quantum states that there must exist non-orthogonal states, that is states that, although different, have a non-z…
No-Signalling Bound on Quantum State Discrimination
Sarah Croke, Erika Andersson, Stephen M. Barnett
Quantum correlations do not allow signalling, and any operation which may be performed on one system of an entangled pair cannot be detected by measurement of the other system alon…
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…
