Another Step In Quantum Computing: A Functional Interconnect

Aug 21

New submitter Gennerik writes: According to a recent article in the MIT Technology Review, a team of international physicists have been able to create a quantum computing interconnect. The interconnect, which is used to connect separate silicon photonic chips, has the important feature of preserving entanglement. This marks a vital step in creating quantum computers that don’t have to work in isolation. According to the article, the trick that

The trick that [University of Bristol Researcher Mark Thomson] and pals have perfected is to convert the path-entanglement into a different kind of entanglement, in this case involving polarization. They do this by allowing the path-entangled photons to interfere with newly created photons in a way that causes them to become polarized. This also entangles the newly created photons, which pass into the optical fiber and travel to the second silicon photonic chip.
