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…
The significance of measurement independence for Bell inequalities and locality
Michael J. W. Hall
A local and deterministic model of quantum correlations is always possible, as shown explicitly by Brans in 1988: one simply needs the physical systems being measured to have a sui…
Complementarity relations for quantum coherence
Shuming Cheng, Michael J. W. Hall
Various measures have been suggested recently for quantifying the coherence of a quantum state with respect to a given basis. We first use two of these, the l_1-norm and relative e…
Experimental test of entropic noise-disturbance uncertainty relations for spin-1/2 measurements
Georg Sulyok, Stephan Sponar, Buelent Demirel +4
Information-theoretic definitions for noise and disturbance in quantum measurements were given in Phys. Rev. Lett. 112, 050401 (2014) and a state-independent noise-disturbance unce…
