A simple technique to generate cluster quantum states of light which are universal resources for quantum computing is disclosed. The technique uses two components. First, a broadband source of Einstein-Podolsky-Rosen entangled states, a.k.a. two-mode-squeezed states, generated in an optical frequency comb from a monochromatic pump field. Second, a phase modulator (typically by electro-optic effect) operating at frequencies multiple of the comb mode spacing. Using only these two components, cluster quantum states can be generated that have one-, two-, three-, or higher-dimensional graphs. The unprecedented compactness of this technique paves the way to implementing quantum computing on chip using quantum nanophotonics.

The proposed method enables to infer, with various degrees of disturbance, the information content of quantum channels. As a possible hacking and security analysis method it exposes and utilizes physical imperfections within common quantum key distribution protocols. It is based on noise injection followed by quantum weak measurements which allow to infer, to some extent, the bits of a distributed secret key. The method can be used for detecting and quantifying the severity of security vulnerabilities within quantum channels. As another application, the proposed method can monitor the performance and error rate of quantum computers.
