Parametric coupling for superconducting qubits
P. Bertet, C. J. P. M. Harmans, J. E. Mooij
We propose a scheme to couple two superconducting charge or flux qubits biased at their symmetry points with unequal energy splittings. Modulating the coupling constant between two…
Dephasing of a flux-qubit coupled to a harmonic oscillator
P. Bertet, I. Chiorescu, C. J. P. M Harmans +1
Decoherence in superconducting qubits is known to arise because of a variety of environmental degrees of freedom. In this article, we focus on the influence of thermal fluctuations…
Relaxation and Dephasing in a Flux-qubit
P. Bertet, I. Chiorescu, G. Burkard +4
We report detailed measurements of the relaxation and dephasing time in a flux-qubit measured by a switching DC SQUID. We studied their dependence on the two important circuit bias…
Spectroscopy on two coupled flux qubits
J. B. Majer, F. G. Paauw, A. C. J. ter Haar +2
We have performed spectroscopy measurements on two coupled flux qubits. The qubits are coupled inductively, which results in a interaction. By applying microwave radia…
Engineering decoherence in Josephson persistent-current qubits
Caspar H. van der Wal, F. K. Wilhelm, C. J. P. M. Harmans +1
We discuss the relaxation and dephasing rates that result from the control and the measurement setup itself in experiments on Josephson persistent-current qubits. For control and m…
Decoherence of the Superconducting Persistent Current Qubit
Lin Tian, L. S. Levitov, Caspar H. van der Wal +5
Decoherence of a solid state based qubit can be caused by coupling to microscopic degrees of freedom in the solid. We lay out a simple theory and use it to estimate decoherence for…
