Spectra of phase point operators in odd prime dimensions and the extended Clifford group
D. M. Appleby, Ingemar Bengtsson, S. Chaturvedi
We analyse the role of the Extended Clifford group in classifying the spectra of phase point operators within the framework laid out by Gibbons et al for setting up Wigner distribu…
A Curious Geometrical Fact About Entanglement
Ingemar Bengtsson
I sketch how the set of pure quantum states forms a phase space, and then point out a curiousity concerning maximally entangled pure states: they form a minimal Lagrangian submanif…
Quantum entanglement
Ryszard Horodecki, Pawel Horodecki, Michal Horodecki +1
All our former experience with application of quantum theory seems to say: {\it what is predicted by quantum formalism must occur in laboratory}. But the essence of quantum formali…
