Chinese scientists demonstrated the first two-dimensional quantum walks of single photons in real spatial space, which may provide a powerful platform to boost analog quantum computing. They reported in a paper published in the journal Science Advances a three-dimensional photonic chip with a scale up to 49-multiply-49 nodes, by using a technique called femtosecond direct writing.
