Quantum Computing and Optically Controlled Electrons

eldavojohn writes "Researchers have released a new paper on quantum computing theorizing how to use optically controlled electrons to make an ultrafast quantum computer. From the article, "Scientists have designed a scheme to create one of the fastest quantum computers to date using light pulses to rotate electron spins, which serve as quantum bits. This technique improves the overall clock rate of the quantum computer, which could lead to the fastest potentially scalable quantum computing scheme of which the scientists are aware.""

But different. I was working with electron spin resonance in solids. The set up used a superconducting magnet and a microwave source. We could actually measure absorption changes when the microwave energy matched the Zeeman split.
There was even some talk about using the set up as a component for quantum computers.

However, the people at the lab have started the discover that the primary relaxation method is fast phonon interactions. This must in fact be the case, otherwise the entire upper band would be overpopulated quicker than detectable. Anyway, as things stood, the materials we worked with proved to be ineffective as quantum switches. The spin property was far too transient.
