    "abstract": "We identify a broad class of physical processes in an optical quantum circuit\nthat can be efficiently simulated on a classical computer: this class includes\nunitary transformations, amplification, noise, and measurements. This\nsimulatability result places powerful constraints on the capability to realize\nexponential quantum speedups as well as on inducing an optical nonlinear\ntransformation via linear optics, photodetection-based measurement and\nclassical feedforward of measurement results, optimal cloning, and a wide range\nof other processes.",
