normalAbstract

The last decade has seen rapidly developing advanced material
technologies. It is possible to investigate previously inaccessible quantum 올림픽 토토
for quantum information and computation in solid-state 올림픽 토토. Especially,
coherent manipulation of quantum states in tunable superconducting devices has
enabled to demonstrate macroscopic qubits and entangled states of qubits.
Experimentally, it has been shown that, in terms of pseudo-spins, a different type
of exchange interactions between two artificial-spins such as an Ising
interaction for charge qubits and flux qubits and an XY interaction for phase
qubits, can be realized and controlled by the system parameters. In this talk,
I will discuss, in a general framework, how artificial-multiple spin
interactions are possible and realizable in superconducting qubit 올림픽 토토. In
fact, flux qubit 올림픽 토토 are shown to have an intrinsic property which is
multiple artificial-spin interactions. Accordingly, flux qubit 올림픽 토토 enable
to study various artificial-spin 올림픽 토토 corresponding to many-body 올림픽 토토
unlikely found naturally. Finally, I will discuss the ranges of system
parameters to generate the Bell
states for two flux qubits, and the10.0pt;font-family:CMR10;mso-bidi-font-family:CMR10;mso-font-kerning:0ptGreenberger-Horne-Zeilinger
