Resonant Activation of a Current-Biased Josephson Junction Near the Classical-Quantum Crossover
Z. E. Thrailkill, J. G. Lambert, S. A. Carabello +1
We examine the resonant activation of a current-biased Josephson junction near the crossover temperature in order to show the way in which the device transitions from the classical…
Multiple Resonators as a Multi-Channel Bus for Coupling Josephson Junction Qubits
Z. E. Thrailkill, J. G. Lambert, R. C. Ramos
Josephson junction-based qubits have been shown to be promising components for a future quantum computer. A network of these superconducting qubits will require quantum information…
Energies and Entanglement in Multiply-coupled Phase Qubit Systems
Z. Thrailkill, S. Kennerly, A. Tyler +1
The superconducting Josephson junction has been demonstrated to be a strong candidate for building quantum bits or "qubits" which are the components of a future quantum computer. I…
Berry's phase in the Josephson phase qubit
Anthony Tyler, Roberto C. Ramos
Berry's phase often appears in quantum two-level systems with a degeneracy. An example of such a system is a spin-1/2 particle in a magnetic field. As the magnetic field is slowly…
