Decoherence In Superconducting Qubits




Decoherence in Superconducting Qubits is an invited workshop focused on the problem of decoherence. The workshop is designed to promote free discussion of the physics of decoherence mechanisms associated with the solid state environment and quantum measurement circuitry. A variety of talks and discussion panels were given by leaders in the field. The following is the list of invited speakers and panelists:



F. Wilhelm
J. Martinis
L. Ioffe
R. Simmonds
Y. Nakamura
