In our previous article, we had an article about quantum teleportation . In today's article, we will talk about how quantum teleportation is mathematically possible. To briefly restate quantum teleportation; Quantum teleportation allows a state vector to be transmitted somewhere without any quantum channels, even at the speed of light distance between them. For this, the following protocol is applied. A long time ago, Alice and Bob shared two qubits in an entangled state with each other. Let Alice's state vector be: The operations on the state vector |ψ> in the above protocol are | ψ 1 >, | ψ 2 >, | ψ 3 > and | ψ 4 >. Let's examine the state vectors one by one. Let's pass the state vector | ψ 1 > through the CNOT and get | ψ 2 > . The first two qubits belong to Alice, and the last qubits to Bob. Now let's go through Hadamard. Now Alice can measure over her two qubits. As a result of the measurements, four results can be obtained with a 25% ...
