Remote Sensing and Control of Phase Qubits
Dale Li, Fabio C. S. da Silva, Danielle A. Braje +2
We demonstrate a remote sensing design of phase qubits by separating the control and readout circuits from the qubit loop. This design improves measurement reliability because the…
Measurement crosstalk between two phase qubits coupled by a coplanar waveguide
Fabio Altomare, Katarina Cicak, Mika A. Sillanpää +8
We analyze the measurement crosstalk between two flux-biased phase qubits coupled by a resonant coplanar waveguide cavity. After the first qubit is measured, the superconducting ph…
RFSQUID-Mediated Coherent Tunable Coupling Between a Superconducting Phase Qubit and a Lumped Element Resonator
M. S. Allman, F. Altomare, J. D. Whittaker +6
We demonstrate coherent tunable coupling between a superconducting phase qubit and a lumped element resonator. The coupling strength is mediated by a flux-biased RF SQUID operated…
Low-loss superconducting resonant circuits using vacuum-gap-based microwave components
Katarina Cicak, Dale Li, Joshua A. Strong +6
We have produced high-quality complex microwave circuits, such as multiplexed resonators and superconducting phase qubits, using a "vacuum-gap" technology that eliminates lossy die…
Controlling coherence using the internal structure of hard pi pulses
Yanqun Dong, R. G. Ramos, Dale Li +1
The tiny difference between hard pi pulses and their delta-function approximation can be exploited to control coherence. Variants on the magic echo that work despite a large spread…
Generating Unexpected Spin Echoes in Dipolar Solids with Pi Pulses
Dale Li, A. E. Dementyev, Yanqun Dong +2
NMR spin echo measurements of C-13 in C60, Y-89 in Y2O3, and Si-29 in silicon are shown to defy conventional expectations when more that one pi pulse is used. Multiple pi-pulse ech…
