Quantum teleportation is a technique discussed in Quantum Information Science to transfer a quantum state to an arbitrarily distant location using an Entangled State and the transmission of some Classical Information . QUANTUM TELEPORTATION: THE RESULT Now, imagine Alice's atom being in some complicated (excited) quantum state. Assume that we do not know this quantum state — and of course, we cannot find out by inspection (measurement). But what we can do is to ''teleport'' the quantum state to Bob's rubidium atom. After this operation, Bob's atom is exactly in the state that Alice's atom was before. Now note that Bob's atom afterwards is indistinguishable from Alice's atom before. In a way, the two are the ''same'' — because it does not make sense to claim that two atoms are different only because they are at different locations. If Alice had gone to Bob and given him the atom we would have exactly the ''same'' physical situation. But Alice and Bob were not required to meet. They only needed to share Entanglement . To see what this means, let us abstract to ). THE METHOD | ||
