Chapter 6, Quantum Networking and Teleportation
- In the Quantum operations for teleportation section, we derive the following formula:
When the initial state of Alice’s qubit is |0⟩, 
= 1 and 
= 0. So, the formula becomes
We have four possibilities, and each possibility has three qubits. Alice measures the middle qubit. When that measurement yields the value 1, Bob applies the X gate. So, we have
No matter what values Alice’s measurements yield, Bob’s qubit is in the |0⟩ state. So the value of Alice’s qubit has been teleported to Bob.
The calculation is similar when the initial state of Alice’s qubit is |1⟩.
