Consider again the entangled state that we saw earlier,

This state is called a Bell state, and it has 3 siblings:

Together, these states form the Bell basis. Write a set of 4 circuits that prepare and return each of the four Bell states.

Learning Objectives:

  • Use this as a reference for all your single- and multi-qubit gate needs!
  • Prepare two-qubit states by combining single- and two-qubit gates.
