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…
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…
Single-Shot Readout of Macroscopic Quantum Superposition State in a Superconducting Flux Qubit
Hirotaka Tanaka, Shiro Saito, Hayato Nakano +3
Single-shot readout experiments were performed on the two lowest-energy states of a superconducting qubit with three Josephson junctions embedded in a superconducting loop. We meas…
Multiphoton transitions in a macroscopic quantum two-state system
S. Saito, M. Thorwart, H. Tanaka +4
We have observed multiphoton transitions between two macroscopic quantum-mechanical superposition states formed by two opposite circulating currents in a superconducting loop with…
