New technique can move fragile quantum data between atoms without destroying it
A qubit walks into a bar, unsure of whether to order drink A or drink B. If the bartender asks the qubit what it wants, the qubit will collapse and be destroyed. But now researchers can instantly teleport the original, intact qubit to another “bar” far away.
In the Jan. 23 Science, a team is reporting what is the first successful transfer of a qubit — an undecided bit of quantum information — between two widely separated, charged atoms.
