Landau-Zener transitions in qubits controlled by electromagnetic fields
Martijn Wubs, Keiji Saito, Sigmund Kohler +2
We investigate the influence of a dipole interaction with a classical radiation field on a qubit during a continuous change of a control parameter. In particular, we explore the no…
Wave Packet Propagation and Electric Conductivity of Nanowires
Munehiko Maeda, Keiji Saito, Seiji Miyashita +1
We compute the electric conductivity of nanowires in the presence of magnetic domain walls by the method of wave packet propagation. We demonstrate that the propagation through the…
Programming physical realizations of quantum computers
Hans De Raedt, Kristel Michielsen, Anthony Hams +2
We study effects of the physical realization of quantum computers on their logical operation. Through simulation of physical models of quantum computer hardware, we analyze the dif…
On the Problem of Programming Quantum Computers
Hans De Raedt, Anthony Hams, Kristel Michielsen +2
We study effects of the physical realization of quantum computers on their logical operation. Through simulation of physical models of quantum computer hardware, we analyse the dif…
Quantum Dynamics in Nanoscale Magnets in Dissipative Environments
Seiji Miyashita, Keiji Saito, Hiroto Kobayashi +1
In discrete energy structure of nanoscale magnets, nonadiabatic transitions at avoided level crossings lead to fundamental processes of dynamics of magnetizations. The thermal envi…
Parity Effect in the Resonant Tunneling
Seiji Miyashita, Keiji Saito, Hiroto Kobayashi
A mechanism of the parity effect in the thermally assisted resonant tunneling is proposed in the view point of nonadiabatic transitions of thermally excited states. In this mechani…
