Entanglement of Electrons Field-Emitted from a Superconductor
Kazuya Yuasa, Paolo Facchi, Rosario Fazio +4
Under appropriate circumstances the electrons emitted from a superconducting tip can be entangled. We analyze these nonlocal correlations by studying the coincidences of the field-…
Lateral Effects in Fermion Antibunching
K. Yuasa, P. Facchi, H. Nakazato +3
Lateral effects are analyzed in the antibunching of a beam of free non-interacting fermions. The emission of particles from a source is dynamically described in a 3D full quantum f…
On the Assumption of Initial Factorization in the Master Equation for Weakly Coupled Systems II: Solvable Models
K. Yuasa, S. Tasaki, P. Facchi +4
We analyze some solvable models of a quantum mechanical system in interaction with a reservoir when the initial state is not factorized. We apply Nakajima-Zwanzig's projection meth…
On the Assumption of Initial Factorization in the Master Equation for Weakly Coupled Systems I: General Framework
S. Tasaki, K. Yuasa, P. Facchi +4
We analyze the dynamics of a quantum mechanical system in interaction with a reservoir when the initial state is not factorized. In the weak-coupling (van Hove) limit, the dynamics…
Control of decoherence: analysis and comparison of three different strategies
P. Facchi, S. Tasaki, S. Pascazio +3
We analyze and compare three different strategies, all aimed at controlling and eventually halting decoherence. The first strategy hinges upon the quantum Zeno effect, the second m…
Control of Decoherence: Dynamical Decoupling versus Quantum Zeno Effect - a case study for trapped ions
S. Tasaki, A. Tokuse, P. Facchi +1
The control of thermal decoherence via dynamical decoupling and via the quantum Zeno effect (Zeno control) is investigated for a model of trapped ion, where the dynamics of two low…
