How contextuality and antidistinguishability are related
Maiyuren Srikumar, Stephen D. Bartlett, Angela Karanjai
Contextuality is a key characteristic that separates quantum from classical phenomena and an important tool in understanding the potential advantage of quantum computation. However…
Decomposition of any quantum measurement into extremals
G. Sentís, B. Gendra, S. D. Bartlett +1
We design an efficient and constructive algorithm to decompose any generalized quantum measurement into a convex combination of extremal measurements. We show that if one allows fo…
Multiple-copy state discrimination: Thinking globally, acting locally
B. L. Higgins, A. C. Doherty, S. D. Bartlett +2
We theoretically investigate schemes to discriminate between two nonorthogonal quantum states given multiple copies. We consider a number of state discrimination schemes as applied…
Mixed state discrimination using optimal control
B. L. Higgins, B. M. Booth, A. C. Doherty +3
We present theory and experiment for the task of discriminating two nonorthogonal states, given multiple copies. We implement several local measurement schemes, on both pure states…
How to perform the most accurate possible phase measurements
D. W. Berry, B. L. Higgins, S. D. Bartlett +3
We present the theory of how to achieve phase measurements with the minimum possible variance in ways that are readily implementable with current experimental techniques. Measureme…
Adaptive Measurements in the Optical Quantum Information Laboratory
H. M. Wiseman, D. W. Berry, S. D. Bartlett +2
Adaptive techniques make practical many quantum measurements that would otherwise be beyond current laboratory capabilities. For example: they allow discrimination of nonorthogonal…
