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…
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…
Stochastic Quantization of Bottomless Systems: Stationary quantities in a diffusive process
Kazuya Yuasa, Hiromichi Nakazato
By making use of the Langevin equation with a kernel, it was shown that the Feynman measure exp(-S) can be realized in a restricted sense in a diffusive stochastic process, which d…
Transition Amplitude within the Stochastic Quantization Scheme -- Perturbative Treatment
Kazuya Yuasa, Hiromichi Nakazato
The quantum mechanical transition amplitudes are calculated perturbatively on the basis of the stochastic quantization method of Parisi and Wu. It is shown that the stochastic sche…
