Sustained, high-fidelity quantum teleportation

Physical qubits are much more sensitive to transmission noise than physical bits. If you want to transmit qubits, teleportation allows you to do it with higher fidelity than by physical transmission.

Why do you want to transmit qubits? For various emerging quantum information technologies, each with different potential economic impact.

Does this mean quantum gizmos will ‘teleport’ the data over space instead of using wires? Like, will a quantum processor pull the data in the quantum ram using teleportation?

Well, not that short range! We are talking about where you have to transmit the qubits at least a few dozen meters.

So perhaps distributed quantum computers spread across a university, city or country.

Also, remember, you still need wired or wireless transmission of bits to do the teleportation protocol.

It means quantum “networking” will be transmitted over classical communications channels.

This simple explanation clicked for me, thank you!
