Questions

1. This chapter’s Quantum operations for teleportation section presents the equations that show why teleportation works. What happens in these equations if the initial state of Alice’s qubit is |0⟩? What happens if the initial state is |1⟩?
2. In Figure 6.10, Alice’s qubit starts in state 0.8228 |0⟩ + 0.5683 |1⟩. Modify this chapter’s generate_amplitudes function as follows:

   def generate_amplitudes():
       alpha = 0.8228
       beta = 0.5683
       return alpha, beta

With this version of generate_amplitudes, what happens when you call the add_gates function? Why?

3. Write Qiskit code to create a circuit of the following kind:

I’ve blurred out the initial amplitudes of Alice’s qubit because you should generate those values randomly.

Run this circuit several times to convince yourself that Bob’s qubit...
