1. A method for generating classical frequency-comb phase references comprising the steps of:
sending a continuous-wave pump field through a bus waveguide and coupled into a microring resonator (MR);
enhancing power of an in-coupled field by an appropriate quality (Q) factor of the MR;
generating side-mode fields via four-wave mixing (FWM), wherein the generating step is above a parametric oscillation threshold;
creating more side-mode fields via stimulated FWM by coupling the generated side-mode fields with the continuous-wave pump field, wherein the creating step provides a spectrum profile;
locking a phase of each frequency tooth of the spectrum profile to generate a Kerr-soliton microcomb;
using the Kerr-solution microcomb as a phase reference for a continuous-variable (CV) cluster state in coherent quantum measurements; and
generating a 3D continuous-variable (CV) cluster state for fault-tolerant quantum computing.
