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…
Asymmetry and decoherence in a double-layer persistent-current qubit
Guido Burkard, David P. DiVincenzo, P. Bertet +2
Superconducting circuits fabricated using the widely used shadow evaporation technique can contain unintended junctions which change their quantum dynamics. We discuss a supercondu…
Nondestructive readout for a superconducting flux qubit
A. Lupascu, C. J. M. Verwijs, R. N. Schouten +2
We present a new readout method for a superconducting flux qubit, based on the measurement of the Josephson inductance of a superconducting quantum interference device that is indu…
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…
