Novel Technique to Record Quantum Mechanical Behavior of an Electron Within a Nanoscale Defect

Researchers at the University of Pennsylvania, University of Chicago, University of California, Santa Barbara and University of Konstanz, Germany, have developed a technique to record the quantum mechanical behavior of an individual electron contained within a nanoscale defect in diamond. Their technique uses ultrafast pulses of laser light both to control the defect’s entire quantum state and observe how that single electron state changes over time.

Diamonds and Nitrogen Atoms Could be Assembled to Create Topologically Protected Quantum Computer

The Quantum Computer is the Holy Grail of quantum technology. Its computing power would eclipse even the fastest classical computers we have today. A team of researchers from TU Wien (Vienna) the National Institute for Informatics (Tokyo) and NTT Basic Research Labs in Japan has now proposed a new architecture for quantum computing, based on microscopic defects in diamond.

Controlled Positioning of Atomic-Scale Diamond Defects May Help Build Better Quantum Computers

By carefully controlling the position of an atomic-scale diamond defect within a volume smaller than what some viruses would fill, researchers have cleared a path toward better quantum computers and nanoscale sensors. They describe their technique in a paper published in the journal Applied Physics Letters, from AIP Publishing.
