These color centers, atomic defects in the diamond\u2019s crystal structure, act as quantum memory capable of storing quantum information.

But qubits are far more sensitive: a single phonon can be enough to change their quantum state\u2014to excite them, or, as in our experiment, to help them relax.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Researchers at the Harvard John A.
