Now, that is a diamond I could really enjoy!
‘Like all diamonds, the diamond used by the researchers has impurities — things other than carbon. The more impurities in a diamond, the less attractive it is as a piece of jewelry, because it makes the crystal appear cloudy.
The team, however, utilized the impurities themselves.
A rogue nitrogen nucleus became the first qubit. In a second flaw sat an electron, which became the second qubit. (Though put more accurately, the “spin” of each of these subatomic particles was used as the qubit.)’
This is exciting!
