Interacting electron spins in solid-state devices could be used for quantum networks, but such spins are often too closely spaced to be individually addressed.

Interacting electron spins in solid-state devices could be used for quantum networks, but such spins are often too closely spaced to be individually addressed. Single-spin control has now been demonstrated for interacting rare-earth dopants. [↧](https://t.co/7TiR7Lm7Zs)
