Density matrix reconstruction from displaced photon number distributions
Jukka Kiukas, Juha-Pekka Pellonpää, Jussi Schultz
We consider state reconstruction from the measurement statistics of phase space observables generated by photon number states. The results are obtained by inverting certain infinit…
State reconstruction formulas for the s-distributions and quadratures
Jukka Kiukas, Juha-Pekka Pellonpää, Jussi Schultz
We consider the method of infinite matrix inversion in the context of quantum state reconstruction. Using this method we give rigorous proofs for reconstruction formulas for the Ca…
Tunneling times with covariant measurements
J. Kiukas, A. Ruschhaupt, R. F. Werner
We consider the time delay of massive, non-relativistic, one-dimensional particles due to a tunneling potential. In this setting the well-known Hartman effect asserts that often th…
On the notion of coexistence in quantum mechanics
P. Busch, J. Kiukas, P. Lahti
The notion coexistence of quantum observables was introduced to describe the possibility of measuring two or more observables together. Here we survey the various different formali…
Position and momentum tomography
Jukka Kiukas, Pekka Lahti, Jussi Schultz
We illustrate the use of the statistical method of moments for determining the position and momentum distributions of a quantum object from the statistics of a single measurement.…
