Researchers at Australia's most eminent and prestigious university, UNSW,
have announced they have developed a qubit from the nucleus of a phosphor atom
built into a silicon substrate which they claim matches the reliability of ion-trap
qubits.
Whereas the ion trap qubits required a vacuum, the researchers state that their
silicon-based technology will be far easier to scale up and manufacture, bringing
the prospect of a practical quantum computer that little bit closer.
They have published their results in Nature.
