Flux Qubits and Readout Device with Two Independent Flux Lines
B. L. T. Plourde, T. L. Robertson, P. A. Reichardt +4
We report measurements on two superconducting flux qubits coupled to a readout Superconducting QUantum Interference Device (SQUID). Two on-chip flux bias lines allow independent fl…

Entangling flux qubits with a bipolar dynamic inductance
B. L. T. Plourde, J. Zhang, K. B. Whaley +7
We propose a scheme to implement variable coupling between two flux qubits using the screening current response of a dc Superconducting QUantum Interference Device (SQUID). The cou…

Decoherence in Josephson-junction qubits due to critical current fluctuations
D. J. Van Harlingen, T. L. Robertson, B. L. T. Plourde +3
We compute the decoherence caused by fluctuations at low frequency in the critical current of Josephson junctions incorporated into flux, phase, charge and hybrid f…
