Oscillations of the purity in the repeated-measurement-based generation of quantum states
B. Militello, K. Yuasa, H. Nakazato +1
Repeated observations of a quantum system interacting with another one can drive the latter toward a particular quantum state, irrespectively of its initial condition, because of a…
Estimation of the Repeatedly-Projected Reduced Density Matrix under Decoherence
H. Nakazato, K. Yuasa, B. Militello +1
Decoherence is believed to deteriorate the ability of a purification scheme that is based on the idea of driving a system to a pure state by repeatedly measuring another system in…
Influence of dissipation on the extraction of quantum states via repeated measurements
B. Militello, K. Yuasa, H. Nakazato +1
A quantum system put in interaction with another one that is repeatedly measured is subject to a non-unitary dynamics, through which it is possible to extract subspaces. This key i…
Solution of the Lindblad Equation in the Kraus Representation
H. Nakazato, Y. Hida, K. Yuasa +3
The so-called Lindblad equation, a typical master equation describing the dissipative quantum dynamics, is shown to be solvable for finite-level systems in a compact form without r…
Measuring the mean value of vibrational observables in trapped ion systems
B. Militello, A. Messina, A. Napoli
The theoretical foundations of a new general approach to the measurement problem of vibrational observables in trapped ion systems is reported. The method rests upon the introducti…
