[SD] 'Flawed' Diamonds Could Speed the Development of Diamond-Based Quantum Computers

A University at Buffalo-led research team has established the presence of a dynamic Jahn-Teller effect in defective diamonds, a finding that will help advance the development of diamond-based systems in applications such as quantum information processing.

"We normally want things to be perfect, but defects are actually very important in terms of electronic applications," said Peihong Zhang, the UB associate professor of physics who led the study. "There are many proposals for the application of defective diamonds, ranging from quantum computing to biological imaging, and our research is one step toward a better understanding of these defect systems."

The research was published online Sept. 30 in Physical Review Letters.

The findings deal with diamonds whose crystal structure contains a particular defect: a nitrogen atom that sits alongside a vacant space in an otherwise perfect lattice made only of carbon.

thats pretty good. ya you typically want a perfect crystal so you can garentee where your electrons are going to go. not only that, the introduction of that nitrogen going to bring costs of that diamond down exponentially

isn't this similar to semiconductor doping? "flawed" would be such an ugly word for an extrinsic semiconductor
