decoherence in josephson qubits from Dielectric Loss
Physical Review Letters, 2005Co-Authors: John M Martinis, K. D. Osborn, David P. Pappas, K. Cicak, Markus Ansmann, Matthias Steffen, R Mcdermott, Seongshik Oh, K Cooper, R. W. SimmondsAbstract:Dielectric Loss from two-level states is shown to be a dominant decoherence source in superconducting quantum bits. Depending on the qubit design, Dielectric Loss from insulating materials or the tunnel junction can lead to short coherence times. We show that a variety of microwave and qubit measurements are well modeled by Loss from resonant absorption of two-level defects. Our results demonstrate that this Loss can be significantly reduced by using better Dielectrics and fabricating junctions of small area & 10 � m 2 . With a redesigned phase qubit employing low-Loss Dielectrics, the energy relaxation rate has been improved by a factor of 20, opening up the possibility of multiqubit gates and algorithms.
