... of ion A. The act of measurement forces it out of superposition and into a definite condition: one of the two qubit states. But because ion A's state is irreversibly tied to ion B's, the measurement ...

"I'm relatively optimistic that we should be able to combine three or more qubits soon," Schoelkopf said. "But to make a system which will actually perform computations on your laptop would ...
... , the scientists have found a novel method for distilling the entanglement by working with two qubits at a time. As the researchers explain, the special properties of bound entanglement could make it ...
... be able to reliably carry information over long distances. The technology to encode useful information on the qubits and subsequently read it back is still lacking, but once those problems are solved, ...
... that carry quantum information are typically fragile, but a new method of combing six photons leads to robust qubits that are immune to many of the effects that threaten to scramble quantum data.
... of angles at which an electron can tilt, there are theoretically an infinite number of values that a qubit can store. Practically speaking, however, the number of available values will be constrained ...
... the challenge had been to create a computer semiconductor in which the quantum state could be controlled, creating a qubit.
