Hybrid quantum magnetic field sensor with an electron spin and a nuclear spin in diamond
Yuichiro Matsuzaki, Takaaki Shimooka, Hirotaka Tanaka +3
Recently, magnetic field sensors based on an electron spin of a nitrogen vacancy (NV) center in diamond have been studied both from an experimental and theoretical point of view. T…
Quantum Zeno effect in an unstable system with NMR
Yuichiro Matsuzaki, Hirotaka Tanaka
We theoretically propose a scheme for verification of quantum Zeno effect (QZE) to suppress a decay process with Nuclear Magnetic Resonance (NMR). Nuclear spins are affected by low…
Electrical Detection and Magnetic-Field Control of Spin States in Phosphorus-Doped Silicon
H. Morishita, L. S. Vlasenko, H. Tanaka +5
Electron paramagnetic resonance of ensembles of phosphorus donors in silicon has been detected electrically with externally applied magnetic fields lower than 200 G. Because the sp…
Two-photon probe of the Jaynes-Cummings model and symmetry breaking in circuit QED
Frank Deppe, Matteo Mariantoni, E. P. Menzel +9
Superconducting qubits behave as artificial two-level atoms and are used to investigate fundamental quantum phenomena. In this context, the study of multi-photon excitations occupi…
Phase-Coherent Dynamics of a Superconducting Flux Qubit with Capacitive-Bias Readout
F. Deppe, M. Mariantoni, E. P. Menzel +7
We present a systematic study of the phase-coherent dynamics of a superconducting three-Josephson-junction flux qubit. The qubit state is detected with the integrated-pulse method,…
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…
