Chaining Atoms collectively Yields Quantum Storage

First printed in PhysOrg on Feb. 16, 2022

Engineers at Caltech have developed an method for quantum storage that might assist pave the best way for the event of large-scale optical quantum networks.

The work, which is described in a paper printed on Feb. 16 within the journal Nature, makes use of a quantum bit (or qubit) comprised of an ion of ytterbium (Yb), a uncommon earth aspect additionally utilized in lasers.

The crew, led by Andrei Faraon, professor of utilized physics and electrical engineering, embedded the ion in a clear crystal of yttrium orthovanadate (YVO4) and manipulated its quantum states by way of a mixture of optical and microwave fields.

The crew then used the Yb qubit to regulate the nuclear spin states of a number of surrounding vanadium atoms within the crystal.

“Based mostly on our earlier work, single ytterbium ions have been identified to be glorious candidates for optical quantum networks, however we would have liked to hyperlink them with further atoms. We exhibit that on this work,” says Faraon, the co-corresponding writer of the Nature paper.

The system was fabricated on the Kavli Nanoscience Institute at Caltech, after which examined at very low temperatures in Faraon’s lab.
