Description

Present section I & II only
  1. Briefly explain the Josephson effect. Why Josephson junction is associated with a nonlinear inductance? 
  2. What is the difference between a transmon and a Cooper pair box?
  3. Why is anharmonicity important for constructing an artificial atom?
  4. What is the trade off between sensitivity and anharmonicity as one increases Ej/Ec ratio?
  5. Explain the mechanical analogue of Josephson junction?
