‘Dark’ Spins in Diamond Could Lead to Room-Temperature Quantum Computing

Researchers at UC Santa Barbara have potentially opened up a new avenue toward room-temperature solid-state quantum information processing.

They discovered previously invisible “dark” (not visually detectable) spins from nitrogen defects in the diamond crystal.

“We have found a channel for moving information between single electron spins at room temperature,” said Awschalom, David Awschalom, a professor of physics. This is an initial step towards spin-based information processing.

The paper, “Anisotropic interactions of a single spin and dark-spin spectroscopy in diamond,” is being published by Nature Physics in November 2005 as the cover article, and is available through advance online publication.
