Technically, it is the bits in those various devices that talk to each other. \u201cFor a normal computer, this poses absolutely no problem,\u201d says professor Lieven Vandersypen. \u201cHowever, for the quantum computer \u2013 which is potentially much faster than the current computers \u2013 that information exchange between quantum bits is very complex, especially over long distances.\u201d<\/p>\n<p><img decoding=\"async\" class=\"aligncenter\" class=\"\" src=\"https:\/\/lifeboat.com\/blog.images\/electron-spins-talk-to-each-other-via-a-quantum-mediator2.jpg\" alt=\"Mediating with quantum dots\" data-id=\"12489\"><br \/>\n<strong>Mediating with quantum dots<\/strong> Artist impression of two electron spins that talk to each other via a \u2018quantum mediator\u2019. The two electrons are each trapped in a semiconductor nanostructure (quantum dot). The two spins interact, and this interaction is mediated by a third, empty quantum dot in the middle. In the future, coupling over larger distances can be achieved using other objects in between to mediate the interaction. This will allow researchers to create two-dimensional networks of coupled spins, that act as quantum bits in a future quantum computer.
