"gAUssian boson sampling"  using a photonic quantum computer "proves quantum supremacy"
A quantum version of a Victorian counting machine just what quantum computers need to race ahead of the pack. Prof. Scott Aaronson of the Massachusetts Institute of Technology (now at UT Austin) suggested tackling this problem by rewinding the technological clock. His idea was to build a quantum version of a Galton board (invented by Victorian scientist Francis Galton) or a quincunx board as a way to study statistical distributions. He suggested that it should be possible to construct a quantum equivalent to the board (a device that uses the laws of quantum, rather than classical, mechanics to perform certain calculations) and that such a device would carry out these calculations faster than a machine using any other method, including conventional computation.
