Tight state-independent uncertainty relations for qubits
Alastair A. Abbott, Pierre-Louis Alzieu, Michael J. W. Hall +1
The well-known Robertson-Schrödinger uncertainty relations have state-dependent lower bounds which are trivial for certain states. We present a general approach to deriving tight s…
A variant of the Kochen-Specker theorem localising value indefiniteness
Alastair A. Abbott, Cristian S. Calude, Karl Svozil
The Kochen-Specker theorem proves the inability to assign, simultaneously, noncontextual definite values to all (of a finite set of) quantum mechanical observables in a consistent…
A Non-Probabilistic Model of Relativised Predictability in Physics
Alastair A. Abbott, Cristian S. Calude, Karl Svozil
Little effort has been devoted to studying generalised notions or models of (un)predictability, yet is an important concept throughout physics and plays a central role in quantum i…
