Is it possible to conduct quantum teleportation with a larger than necessary e-dit and preserve entanglement?
Suppose you have an e-bit between qubits A and B. You want to transfer the state of qubit Q to B. You can utilize this e-bit to perform a quantum teleportation to achieve this.
Now instead suppose ...

In quantum teleportation when exactly the original EPR pair stops being entangled?
In quantum teleportation Alice and Bob share a pair of entangled particles (EPR pair made of particles 2 and 3, for example). Alice has another particle (1) whose quantum state she wants to send to ...

Teleportation and boosted observer, special relativity
According to relativistic quantum information, entanglement, purity of states are not Lorentz invariant.
Here I check such a problem. If we have two coordinate systems $R_A,R_B$ with relative ...

Continuous-variable teleportation circuit using finite squeezing
I am studying the continuous variable teleporting circuit using a vacuum squeezed state showed by Weedbrook, pag. 39-40. Section: Gaussian errors from finite squeezing; in that, they propose an ...

How are joint measurements of quantum states realized experimentally?
I have a question regarding the experimental implementation of joint measurements of quantum states.
While I understand for example the teleportation protocol using Bell states, something that still ...

Communication via teleportation/entanglement (FTL communication)
I know this has been asked many times, but I have a hard time "crystallising" it in my mind.
First: let's say we teleport a DVD (with quantum teleportation). Isn't this FTL communication?
Second: ...
