The thermoelectric effect can be used to produce entangle photons, according to scientists from Finland, Russia, China and the USA. The proof-of-concept device is superconducting and has layered graphene (green) and metal (blue) electrodes on a silicon dioxide substrate (grey). “Superconductivity is caused by entangled pairs of electrons called Cooper pairs,” said Nikita Kirsanov of Aalto ...
