Reading quantum data

“Our work represents a breakthrough in the search for a nanoscopic [atomic scale] mechanism that could be used for a data readout device,” says Christoph Boehme, assistant professor of physics at the University of Utah. “We have demonstrated experimentally that the nuclear spin orientation of phosphorus atoms embedded in silicon can be measured by very subtle electric currents passing through the phosphorus atoms.”The study by Boehme and colleagues in Germany will be published in the December issue of the journal Nature Physics and released online Sunday, Nov. 19.

“We have resolved a major obstacle for building a particular kind of quantum computer, the phosphorus-and-silicon quantum computer,” says Boehme. “For this concept, data readout is the biggest issue, and we have shown a new way to read data.”
