Scientists from Yokohama National University in Japan have found a way to accurately manage the cubes without previous restrictions, and the results of the study are published in Nature Photos.
"Microvolons are usually used for individual quantum control, but the individual wiring of microwave lines is required," says the author of the article Hideo Kosaka, "On the other hand, light can be used locally, but not accurately, to manipulate the cubes."
Kosaka and other physicists demonstrated the control of the cubes by manipulating the electron's back by combining microwave manipulations and local optical shifts of the transformational frequencies of the atoms and molecules. This process is known as Stark's shift.
In other words, they were able to combine optical methods based on laser light with microwaves to overcome previous limitations.
Researchers have also shown that this electronic back control can, in turn, control the nuclear back of the nitrogen atom in the nitrogen-vacansion centre, as well as the interaction between the electronic back and the nuclear back, which is important because it can accurately control the cubes without connection problems.
The area of quantum computing has the potential to perform tasks that are too complex for traditional computers and at high speeds. However, the development of large-scale quantum processors and quantum memory devices is essential to begin with. The precise management of cubes — or quantum bits, the main building blocks of quantum computers — is crucial to this process. But the management of cubes has limitations on massive high-density wiring with high accuracy.
