(HighTechDeck) Quantum teleportation involves sending data from one ion to a completely separate one. Previous attempts at quantum teleportation were limited to data fragments, but the NIST team have managed to teleport an entire quantum logic operation.
NIST physicist Dietrich Leibfried says: “We verified that our logic operation works on all input states of two quantum bits with 85 to 87% probability — far from perfect, but it is a start.”
Quantum teleportation of logic operations could be an effective way to conduct operations between qubits – quantum bits – thus allowing for the development of quantum computers.
“Gate teleportation allows us to perform a quantum logic gate between two ions that are spatially separated and may have never interacted before,” Leibfried says. “The trick is that they each have one ion of another entangled pair by their side, and this entanglement resource, distributed ahead of the gate, allows us to do a quantum trick that has no classical counterpart.”
