Alice and Bob share a state a|++> + b|-->, where the first qubit is Alice's and the second qubit is Bob's. Alice measures her qubit in the standard basis and sends the measurement
outcome to Bob. If Bob wants his qubit in a|+> + b|->, what gate does he apply in the following two cases? Choose your answer from I,X,Z,H.

Alice's outcome is 0:

Alice's outcome is 1:

  • Quantum Physics -

    I
    X

  • Quantum Physics -

    Wrongggg

  • Quantum Physics -

    Alice's outcome is 0: H

    Alice's outcome is 1: X,H
