Quantum dots: Through locks to narrows

In semiconductor quantum dots, single electron spins are surrounded by a bath of nuclear spins. Controlling the nuclear magnetization is difficult, but two experiments now demonstrate locking of the average nuclear field to a particular value and narrowing of the nuclear randomness.
