Open Quantum System Dynamics from a Measurement Perspective: Applications to Coherent Particle Transport and to Quantum~Brownian Motion
Open Quantum System Dynamics a Measurement Perspective Applications Coherent Particle Transport Quantum~Brownian Motion
2010/10/20
We employ the theoretical framework of positive operator valued measures, to study Markovian open quantum systems. In particular, we discuss how a quantum system in uences its environment, or parts th...
On the Contractivity of Hilbert-Schmidt distance under open system dynamics
Hilbert-Schmidt distance system dynamics
2010/4/12
We show that the Hilbert-Schmidt distance, unlike the trace distance, between quantum states is generally not monotonic for open quantum systems subject to Lindblad semigroup dynamics. Sufficient cond...
