Optimal Heisenberg-style bounds for the average performance of arbitrary phase estimates
Dominic W. Berry, Michael J. W. Hall, Marcin Zwierz +1
The ultimate bound to the accuracy of phase estimates is often assumed to be given by the Heisenberg limit. Recent work seemed to indicate that this bound can be violated, yielding…
Comment on "Geometric derivation of the quantum speed limit"
Marcin Zwierz
Recently, Jones and Kok [P. J. Jones and P. Kok, Phys. Rev. A 82, 022107 (2010)] presented alternative geometric derivations of the Mandelstam-Tamm [L. Mandelstam and I. Tamm, J. P…
High-efficiency cluster-state generation with atomic ensembles via the dipole-blockade mechanism
Marcin Zwierz, Pieter Kok
We demonstrate theoretically a scheme for cluster state generation, based on atomic ensembles and the dipole blockade mechanism. In the protocol, atomic ensembles serve as single q…
Long-range dependencies in heart rate signals- revisited
Danuta Makowiec, Rafal Galaska, Aleksandra Dudkowska +2
The RR series extracted from human electrocardiogram signal (ECG) is considered as a fractal stochastic process. The manifestation of long-range dependencies is the presence of pow…
