A Simple Scheme to Entangle Distant Qubits from a Mixed State via an Entanglement Mediator
Kazuya Yuasa, Hiromichi Nakazato
A simple scheme to prepare an entanglement between two separated qubits from a given mixed state is proposed. A single qubit (entanglement mediator) is repeatedly made to interact…
Distillation of Entanglement between Distant Systems by Repeated Measurements on Entanglement Mediator
G. Compagno, A. Messina, H. Nakazato +3
A recently proposed purification method, in which the Zeno-like measurements of a subsystem can bring about a distillation of another subsystem in interaction with the former, is u…
A Purification Scheme and Entanglement Distillations
Hiromichi Nakazato, Makoto Unoki, Kazuya Yuasa
A purification scheme which utilizes the action of repeated measurements on a (part of a total) quantum system is briefly reviewed and is applied to a few simple systems to show ho…
Modified Fowler-Nordheim Field-Emission Formulae from a Nonplanar-Emitter Model
Kazuya Yuasa, Ayumi Shimoi, Ichiro Ohba +1
Field emission formulae, current-voltage characteristics and energy distribution of emitted electrons, are derived analytically for a nonplanar (hyperboloidal) metallic emitter mod…
Optimization of a Neutron-Spin Test of the Quantum Zeno Effect
Paolo Facchi, Yoichi Nakaguro, Hiromichi Nakazato +3
A neutron-spin experimental test of the quantum Zeno effect (QZE) is discussed from a practical point of view, when the nonideal efficiency of the magnetic mirrors, used for filter…
Quantum stochastic resonance in driven spin-boson system with stochastic limit approximation
Kentaro Imafuku, Kazuya Yuasa, Ichiro Ohba
After a brief review of stochastic limit approximation with spin-boson system from physical points of view, amplification phenomenon-stochastic resonance phenomenon-in driven spin-…
