内容摘要：Quantum computers promise to deliver enormous computational power and solve problems that cannot be tackled by ordinary (classical) machines. There are many hardware platforms on which quantum computing can be developed, and it is not yet clear which technology, or combination of technologies, will prove most successful. Today I will give an overview of quantum photonic microprocessors. In the computing architecture used to implement this quantum sampling algorithm, squeezed states of light are generated and launched into an optical network consisting of several optical paths and beam splitters. The squeezed states mix together when they meet in beam splitters because of a quantum effect called interference. As a result, all the states come out completely scrambled, in a way that depends on the relative lengths of the optical paths, known as their relative phases. Reprogramming these phases alters the type of scrambling. After scrambling, the number of photons in each output of this quantum circuit is counted using highly sensitive detectors. The quantum computer is implemented their photonic circuit on a silicon chip technology that is compatible
