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…
Local Fault-tolerant Quantum Computation
Krysta M. Svore, Barbara M. Terhal, David P. DiVincenzo
We analyze and study the effects of locality on the fault-tolerance threshold for quantum computation. We analytically estimate how the threshold will depend on a scale parameter r…
Determination of the tunnel rates through a few-electron quantum dot
R. Hanson, I. T. Vink, D. P. DiVincenzo +4
We demonstrate how rate equations can be employed to find analytical expressions for the sequential tunneling current through a quantum dot as a function of the tunnel rates, for a…
Security Trade-offs in Ancilla-Free Quantum Bit Commitment in the Presence of Superselection Rules
D. P. DiVincenzo, J. A. Smolin, B. M. Terhal
Security trade-offs have been established for one-way bit commitment in quant-ph/0106019. We study this trade-off in two superselection settings. We show that for an `abelian' supe…
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…
