A new type of quantum computing called boson sampling is capable of calculations that no classical computer could accomplish in any reasonable amount of time. This is the second time a quantum algorithm has claimed to achieve this feat, known as quantum supremacy, after Google made a claim of quantum supremacy using its Sycamore device in 2019.
Boson sampling relies on a strange quantum property of photons – particles of light – that is displayed when they travel through a beam splitter, which splits a single beam of light into two beams propagating in different directions. If two identical photons hit the beam splitter at exactly the same time, they will not split from one another, instead they stick together and both travel in the same direction.
If you shoot many photons through
