Résumé : Frequency measurement is probably the most accurate, precise and universally distributed form of metrology.  In this context the frequency comb provides an ideal orthonormal basis for realizing and distributing of quantum entanglement.  Entanglement in microwave frequency combs can be created with superconducting circuits operating at millikelvin temperatures, and recent progress with microwave digital signal processing has enabled methods to control and measure this entanglement.  The talk will discuss our ongoing experimental effort to realize microwave cluster states through phase-coherent multifrequency pumping of a Josephson parametric oscillator.
