摘要
Systems and methods are disclosed for generating cluster quantum states usable for quantum computing. An example system can generate a plurality of qumodes. The plurality of qumodes can include at least two successive qumodes in frequency domain, wherein a frequency spacing between two successive qumodes is equal to a free-spectral range of an optical frequency comb. The plurality of qumodes can include a plurality of bipartite entangled states. A cluster quantum state can be generated by modulating a phase of a portion of the optical fields associated with the plurality of qumodes received from the optical frequency comb, at one or more modulation frequencies. In some embodiments, each of the one or more modulation frequencies can be equal to an integral multiple of the free-spectral-range. In certain embodiments, a property of a cluster graph (such as a dimension of the cluster graph) associated with the cluster quantum state can be controlled by adjusting one or more modulation frequencies.
