Parametric control of a superconducting flux qubit
S. Saito, T. Meno, M. Ueda +3
Parametric control of a superconducting flux qubit has been achieved by using two-frequency microwave pulses. We have observed Rabi oscillations stemming from parametric transition…
Gutzwiller study of spin-1 bosons in an optical lattice under a magnetic field
Takashi Kimura, Shunji Tsuchiya, Makoto Yamashita +1
We study spin-1 bosons in an optical lattice under a magnetic field by the Gutzwiller approximation. Our results thus obtained join the discontinuous phase boundary curves obtained…
Charged exciton emission at 1.3 m from single InAs quantum dots grown by metalorganic chemical vapor deposition
N. I. Cade, H. Gotoh, H. Kamada +4
We have studied the emission properties of self-organized InAs quantum dots (QDs) grown in an InGaAs quantum well by metalorganic chemical vapor deposition. Low-temperature photolu…
Nanoscale atomic waveguides with suspended carbon nanotubes
V. Peano, M. Thorwart, A. Kasper +1
We propose an experimentally viable setup for the realization of one-dimensional ultracold atom gases in a nanoscale magnetic waveguide formed by single doubly-clamped suspended ca…
Coherent control of a flux qubit by phase-shifted resonant microwave pulses
Tatsuya Kutsuzawa, Shiro Saito, Hirotaka Tanaka +3
The quantum state of a flux qubit was successfully pulse-controlled by using a resonant microwave. We observed Ramsey fringes by applying a pair of phase-shifted pi/2 microwave pul…
