How is quantum teleportation possible when there's a continuum of possible states to send over?
I'm trying to understand quantum teleportation and I was wondering if anyone could provide an intuition about it. I have seen the derivation but it still bugs me.
You start with an entangled pair of ...

Can a non-entangled qubit be teleported by entangling it?
Let's say I have a qubit that is not entangled in state $\psi$. I want to teleport this qubit by entangling it with another qubit but still getting $\psi$ back in the end.
Is this possible, or would ...

Quantum teleportation of atomic states that involve energy [duplicate]
With quantum computing the concern is with information, and when quantum teleportation appears, the states being transferred are often spin states.
However, there is an energy difference, even if ...

Quantum Teleportation Fidelity
I understand that quantum teleportation fidelity is the overlap of the initial quantum state with the teleported quantum state. If the teleportation is perfect, then the fidelity would equal 1 or 100% ...
