Gleason's theorem for composite systems
Markus Frembs, Andreas Döring
Gleason's theorem [A. Gleason, J. Math. Mech., \textbf{6}, 885 (1957)] is an important result in the foundations of quantum mechanics, where it justifies the Born rule as a mathema…
From no-signalling to quantum states
Markus Frembs, Andreas Döring
Characterising quantum correlations from physical principles is a central problem in the field of quantum information theory. Entanglement breaks bounds on correlations put by Bell…
No-signalling, Contextuality, and the Arrow of Time
Markus Frembs, Andreas Döring
Bell's seminal paper shows that some correlations in quantum theory are not reconcilable with hidden variables and the classical notion of locality. Yet, a weaker notion of localit…
Contextuality as a resource for measurement-based quantum computation beyond qubits
Markus Frembs, Sam Roberts, Stephen D. Bartlett
Contextuality - the obstruction to describing quantum mechanics in a classical statistical way - has been proposed as a resource that powers quantum computing. The measurement-base…
