A defect-riddled, boron- and silicon-laced synthetic is a real gem at storing and sending data
A new kind of artificial diamond is a cut above the rest for quantum memory.
Unlike other synthetic diamonds, which could either store quantum information for a long time or transmit it clearly, the new diamond can do both. This designer crystal, described in the July 6 Science, could be a key building block in a quantum internet. Such a futuristic communications network would allow people to send supersecure messages and connect quantum computers around the world (SN: 10/15/16, p. 13).
Synthetic diamond can serve as quantum storage thanks to a type of flaw in its carbon lattice, where two neighboring carbon atoms are replaced with one noncarbon atom and an empty space (SN: 4/5/08, p. 216). This pairing
