UChicago scientists fireworks atoms ultra-low temperatures
2017/11/23
Scientists aren’t normally treated to fireworks when they discover something about the universe. But a team of University of Chicago researchers found a show waiting for them at the atomic level—along...
Phosphorus Spin Coherence Times in Silicon at Very Low Temperatures
magnetic resonance donor spins in silicon quantum computing
2010/10/27
Phosphorus donor spin coherence in isotopically pure 28 silicon is measured at very low temperatures using pulsed electron spin resonance. The isolated spin T2 varies unexpectedly with phosphorus conc...
In a recent paper [Beige, Knight, and Vitiello, quant-ph/0404160], we showed that a large number N of particles
can be cooled very efficiently. The particles should be excited by red-detuned laser fi...
