Description

  1. Explain the excitation swapping between qubit and the resonator shown in Fig1c&d
  2. Describe the set of operations (Q,S,Z) used on qubit and resonator based on Eq(1)
  3. How is the sequence designed to synthesize an arbitrary state, how are complex state coefficients constructed
  4. How to do Wigner tomography on the synthesized state, how is the parity measurement performed
  5. What's the difference between |0\rangle+|3\rangle and |0\rangle+e^{i\cdot\phi}|3\rangle in terms of Wigner function, why does the relative phase of Fock states correspond to a global rotation of the Wigner function
  6. How are phases of Fock state superposition (density matrix) measured
