Visualizing the Quantum Interaction Picture in Phase Space
Bahar Mehmani, Andrea Aiello
We illustrate the correspondence between the quantum Interaction Picture-evolution of the state of a quantum system in Hilbert space and a combination of local and global transform…
An overview on Single Apparatus Quantum Measurements
Bahar Mehmani, Theo M. Nieuwenhuizen
Given the state of a quantum system, one can calculate the expectation value of any observable of the system. However, the inverse problem of determining the state by performing di…
Post-adiabatic forces and Lagrangians with higher-order derivatives
A. E. Allahverdyan, B. Mehmani
We study a slow classical system [particle] coupled to a fast quantum system with discrete energy spectrum. We adiabatically exclude the quantum system and construct an autonomous…
Quantum state tomography using a single apparatus
B. Mehmani, A. E. Allahverdyan, Th. M. Nieuwenhuizen
The density matrix of a two-level system (spin, atom) is usually determined by measuring the three non-commuting components of the Pauli vector. This density matrix can also be obt…
Simultaneous Measurement of Non-Commuting Observables
G. Aquino, B. Mehmani
It is shown that the full unknown state of a spin-1/2 system, S, which, within Born's statistical interpretation, is meant as the state of an ensamble of identically prepared syste…
