In 1998, researchers including Mark Kubinec of UC Berkeley performed one of the first simple quantum computations using individual molecules. They used pulses of radio waves to flip the spins of two nuclei in a molecule, with each spin’s “up” or “down” orientation storing information in the way that a “0” or “1” state stores information in a classical data bit.

In those early days of quantum computers, the combined orientation of the two nuclei—that is, the molecule’s quantum state—could only be preserved for brief periods in specially tuned environments. In other words, the system quickly lost its coherence. Control over quantum coherence is the missing step to building scalable quantum computers.
