A single electron can now be observed, controlled and manipulated by lasers thanks to a team of researchers at the University of Chicago.

According to Austrian Tribune, "To observe, control and manipulate the behavior of a single electron at the quantum mechanical level, the team of researchers made use of laser light in ultrafast pulses. The laser light successfully managed the quantum state of electron present inside nanoscale defect, which is found in naturally-found diamonds."

The tool could also observe and track the properties of the single electron in addition to how the electron changes over time. At the center of the study is a quantum spin system, also known as called nitrogen-vacancy center. 

It was a test-bed system for creating and developing semiconductor quantum bits and other microscopic technology, lead author of the study David Awschalom explained.

The findings suggest that researchers have now taken the next step in molecular computing and much faster information processing. Quantum computing technologies are expected to provide a much faster and convenient way of computing in the future.

According to Angle Chronicle, "This experiment also emphasized the power of light in controlling the quantum state at ridiculously increased velocity. Aside from its future use in semiconductor production, this study can also provide a new measuring tool for this tiny particles of matter."

The findings on laser controlling a single electron were published in the journal Science Express.
