  • A Team of Researchers make First Quantum Computer Bridge

Apparently, a team of researchers has made the first quantum computer bridge using diamond and silicon.

Via a forceful imbedding of two silicon atoms in a diamond base, a team of researchers has made a single microchip. This contains all the components that are required to make a quantum bridge that will link quantum computers to each other.

Small quantum computers have already been made. It is being surmised that maybe the best quantum computer is not a giant one but several small ones linked in a cluster of sorts.

By using an array of quantum data that is dealt out on a bridge or network, new types of quantum sensing could be allowed to take place. Quantum correlations are something that allow all the atoms in a network to behave in a manner similar to a single atom.

This is thus a collective action that takes place in quantum computers. The experiment which took place involved the usage of a concentrated ion beam implanter.

Single ions were destroyed in concise locations on a diamond substrate. This implantation method was used to replace a carbon atom of the diamond with a bigger silicon atom.

The two carbon atoms on either side of the silicon atom flew off due to the paucity of space when this operation took place. Thus the silicon atom was left behind as a kind of large occupier of space.

It was buffered againt loose electrical currents by the non-conductive vacancies on the sides. While such silicon atoms are located in a solid, they act like they were floating in gas.

Thus their electrons’ reaction to quantum stimulation was not obfuscated by matter. The whole operation consisted of putting the silicon atoms exactly where they were supposed to be.

Thousands of such imbedded sites can be created which would help the quantum computers function with alacrity and efficiency. The atoms are implanted below the surface of the substrate and annealed in place.

Before this novel method, the scientists had to engage in a backbreaking series of maneuvers to accomplish this act. Once the silicon atoms are in place, laser-produced photons cause these atoms to go into higher atomic energy states.

When these atoms reach lower states ultimately, they emit the photons. This experiment holds great meaning for the future of quantum computing.

The findings of this study got published in the current issue of the journal Science.
