Noise-correlation spectrum for a pair of spin qubits in silicon
J. Yoneda, J. S. Rojas-Arias, P. Stano +5
Semiconductor qubits are appealing for building quantum processors as they may be densely integrated due to small footprint. However, a high density raises the issue of noise corre…
Preparation and Readout of Multielectron High-Spin States in a Gate-Defined GaAs/AlGaAs Quantum Dot
H. Kiyama, K. Yoshimi, T. Kato +3
We report the preparation and readout of multielectron high-spin states, a three-electron quartet, and a four-electron quintet, in a gate-defined GaAs/AlGaAs single quantum dot usi…
Symmetry Breaking in Bose-Einstein Condensates
Masahito Ueda, Yuki Kawaguchi, Hiroki Saito +2
A gaseous Bose-Einstein condensate (BEC) offers an ideal testing ground for studying symmetry breaking, because a trapped BEC system is in a mesoscopic regime, and situations exist…
Quantum Monte-Carlo method without negative-sign problem for two-dimensional electron systems under strong magnetic fields
Sei Suzuki, Tatsuya Nakajima
The quantum Monte-Carlo method is applied to two-dimensional electron systems under strong magnetic fields. The negative-sign problem involved by this method can be avoided for cer…
Nambu-Goldstone Mode in a Rotating Dilute Bose-Einstein Condensate
Masahito Ueda, Tatsuya Nakajima
The Nambu-Goldstone mode, associated with vortex nucleation in a harmonically confined, two-dimensional dilute Bose-Einstein condensate, is identified with the lowest-lying envelop…
Formulation and Application of Quantum Monte Carlo Method to Fractional Quantum Hall Systems
Sei Suzuki, Tatsuya Nakajima
Quantum Monte Carlo method is applied to fractional quantum Hall systems. The use of the linear programming method enables us to avoid the negative-sign problem in the Quantum Mont…
