Measurement uncertainty relations: characterising optimal error bounds for qubits
Tom Bullock, Paul Busch
In standard formulations of the uncertainty principle, two fundamental features are typically cast as impossibility statements: two noncommuting observables cannot in general both…
Quantum Measurements Constrained by Symmetries
P. Busch, L. D. Loveridge
We revisit the theorem of Wigner, Araki and Yanase (WAY) describing limitations to repeatable quantum measurements that arise from the presence of conservation laws. We will review…
Multi-slit interferometry and commuting functions of position and momentum
J. C. G. Biniok, P. Busch
In a recent, modified double-pinhole diffraction experiment the existence of an interference pattern was established indirectly along with a near-perfect imaging of the double pinh…
'Measurement of Quantum Mechanical Operators' Revisited
Leon Loveridge, Paul Busch
The Wigner-Araki-Yanase (WAY) theorem states a remarkable limitation to quantum mechanical measurements in the presence of additive conserved quantities. Discovered by Wigner in 19…
