Quantum Computing To Get A Giant Leap With The World's First Quantum Bridge From Sandia Labs

Using an optical instrument you probably vow to zoom the world around, but the exotic quantum world that governs the parts and parcels are vague, complicated with respect to our general comprehension. In layman terms, we know that communication is one of the most important aspects of a group work. Inclined to the social networking sites, we browse other profiles, make friends, poke others and many of the times establish a successful friendship rather a connection which simply passes information from one side to other. What’s interesting here, Sandia Labs in collaboration with Havard University has made the world’s first quantum bridge on a single chip that connects the quantum computers.

Artist's Interpretation of The Quantum Bridge

Sandia researcher Ryan Camacho believes that the next big quantum computer might involve small computers clubbed together. Plus distributing quantum information through networks could unravel forms of quantum sensing as quantum correlation helps different atoms in the network to behave as they exist as single atoms. To achieve the bridge, the team had chosen a diamond substrate, upon which single ions were penetrated on to the precise location with the help of an ion beam implanter.

The trio - Ed Bielejec, Jose Pacheco, and Daniel Perry explained that the implantation technique was used to replace a carbon atom from the middle of the diamond lattice with a silicon atom. After incorporating the silicon atoms, other carbon atoms surrounding the structure leave the frame which finally allows silicon to be the prime component. Although the silicon is embedded in the solid, it behaves as if it is placed in a gaseous environment.

After assuring a temporary settlement Laser-originated photons energize silicon electrons, pushing them to the higher energy state. Not breaking the rule, to gain the stability when electrons come back to the low energy state quantum of photons leave the site. Modifying the properties of EM waves including intensity, polarization information is passed as if through a wired channel. The team further implied that the work not only has theoretical value they have already devised a prototype version explaining the outcomes. The complete document research report has now been published in the Journal “Science”.
