Objectives

  • Measurement and optimization of the coherence time in Josephson quantum circuits
  • Realization of measurement techniques with the required sensitivity in the (very short)
    available measuring time without destroying the information about the quantum system
  • Realization of single qubit operations in charge and fluxon qubits
  • Realization of controlled-not or other entangling gates
  • Development of the necessary control electronics
  • Development of junction fabrication without shadow evaporation
  • Development of quantum algorithms and error correcting schemes for qubit systems
  • Development of a schematic lay-out of a possible future Josephson quantum computer,
    analysis of the required precision of fabrication and time control
  • The identification of the necessary following steps, and the formulation of a "Road map"
    for superconductivity based quantum computation
