By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
First, a Quantum Computer bridge is something that has the ability to link quantum computers together. Sandia researcher Ryan Comacho explains that the first quantum computer may not be one large unit, but "a group of smaller ones" all connected. This would also allow various forms of quantum sensing, since this bridge would allow all of the atoms in the network to have the ability to act as one single atom.
Researchers at Sandia have teamed up with scientists from Harvard University to make this plan a reality. They used a focused ion beam implanter for blasting single ions into precise locations on a diamond substrate. The researchers then used the implanter to replace one of the carbon diamond atoms with a larger silicon atom. These silicon atoms would force the carbon atoms to evacuate. This then leaves the silicon atoms alone in space. Even though these silicons are in solids, they act as though they are in a gas. These particles have no other molecules to interfere with them, so they are able to freely transfer the quantum information.
