Steering, incompatibility, and Bell inequality violations in a class of probabilistic theories
Neil Stevens, Paul Busch
We show that connections between a degree of incompatibility of pairs of observables and the strength of violations of Bell's inequality found in recent investigations can be exten…
Quantum root-mean-square error and measurement uncertainty relations
Paul Busch, Pekka Lahti, Reinhard F Werner
Recent years have witnessed a controversy over Heisenberg's famous error-disturbance relation. Here we resolve the conflict by way of an analysis of the possible conceptualizations…
Measurement uncertainty relations
Paul Busch, Pekka Lahti, Reinhard F Werner
Measurement uncertainty relations are quantitative bounds on the errors in an approximate joint measurement of two observables. They can be seen as a generalization of the error/di…
Heisenberg uncertainty for qubit measurements
Paul Busch, Pekka Lahti, Reinhard F Werner
Reports on experiments recently performed in Vienna [Erhard et al, Nature Phys. 8, 185 (2012)] and Toronto [Rozema et al, Phys. Rev. Lett. 109, 100404 (2012)] include claims of a v…
An operational link between MUBs and SICs
Roberto Beneduci, Tom Bullock, Paul Busch +3
We exhibit an operational connection between mutually unbiased bases and symmetric infomationally complete positive operator-valued measures. Assuming that the latter exists, we sh…
Proof of Heisenberg's error-disturbance relation
Paul Busch, Pekka Lahti, Reinhard F. Werner
While the slogan "no measurement without disturbance" has established itself under the name Heisenberg effect in the consciousness of the scientifically interested public, a precis…
