Building quantum machines out of light

Light has the remarkable capacity to reveal quantum features under ambient conditions, making exploration of the quantum world feasible in simple laboratory experiments. Further, the availability of high-quality integrated optical components makes it possible to conceive of large-scale quantum states by bringing together many different quantum light sources and manipulating them in a coherent manner and detecting them efficiently. By this route, we can envisage a scalable photonic quantum network, that will facilitate the preparation of distributed quantum correlations among  many light beams. This will enable a new regime of state complexity to be accessed - one in which it is impossible using classical computers to determine the structure and dynamics of the system: Photonic quantum machines will therefore open new frontiers in quantum science and technology.
