  1. EPR Pairs and Quantum Teleportation 2005/08/11

  2. A H A’ B B’ In Out 00 01 10 11 EPR Pairs • Quantum circuit to create EPR pairs • True table

  3. M1 H M2 XM2 ZM1 Quantum Teleportation • Alice and Bob met long ago but now live far apart. While they were together, they generated an EPR pair and each took one qubit away. Now Alice wants to deliver a qubit (|α›) to Bob.

  4. Quantum Teleportation (contd.) • State0 (initial state)

  5. Quantum Teleportation (contd.) • State1 (pass CN gate)

  6. Quantum Teleportation (contd.) • State2 (pass Hadamard gate)

  7. Quantum Teleportation (contd.) • [Pauli Matrices]

  8. Quantum Teleportation (contd.) • Measure • If M1M2=00 → → M1M2=01 → → M1M2=10 → → M1M2=11 → →
