Direct estimation of decoherence rates
Vladimír Bužek, Peter Rapcan, Jochen Rau +1
The decoherence rate is a nonlinear channel parameter that describes quantitatively the decay of the off-diagonal elements of a density operator in the decoherence basis. We addres…
Quantum homogenization and state randomization in semi-quantal spin systems
Matyas Koniorczyk, Arpad Varga, Peter Rapcan +1
We investigate dynamics of semi-quantal spin systems in which quantum bits are attached to classically and possibly stochastically moving classical particles. The interaction betwe…
Direct versus measurement assisted bipartite entanglement in multi-qubit systems and their dynamical generation in spin systems
Matyas Koniorczyk, Peter Rapcan, Vladimir Buzek
We consider multi-qubit systems and relate quantitatively the problems of generating cluster states with high value of concurrence of assistance, and that of generating states with…
