The researchers say that they have come up with a way for recording and controlling the behavior of a single electron at quantum mechanical level, through which information processing and quantum computing can be brought 1 step closer.
A research team that is headed by the scientists of University of Chicago reports that laser light should be used in ultrafast pulses for controlling the quantum state of electrons that are contained inside nanoscale defects that are located in a diamond and also observing changes in the electron over a period of time.
The researchers put their focus on the quantum mechanical property of electrons that are known as spin. In a manner like the way bits of data are held up by conventional computers, either a binary 1 or 0 or the charge state of an electron in a quantum based computer spin states of individual electrons would represent a quantum bit.
At the center, as per the research of the team, there is a quantum spin system which is known as nitrogen-vacancy center, an atomic-scale defect which is found to be occurign in diamonds naturally.
In the NV center, there is a single atom of nitrogen that sits adjacent to an empty point in the crystalline latticework of the diamond.
A molecular engineering professor and Chicago and David Awschalom, says “”These defects have garnered great interest over the past decade, providing a test-bed system for developing semiconductor quantum bits as well as nanoscale sensors,”
Here, they have an ability of harnessing light for completely controlling the quantum state of this defect at very high speeds. A single NV center could be illuminated with 2 pulses of light from a laser, each was less than millionth of a millionth of a second.
