Methods are disclosed for generating, manipulating, and controlling non-Gaussian quantum states in continuous variable cluster quantum states usable for quantum computing. Some methods can be used to generate, transport, and enlarge Schrödinger-Cat states embedded in the CV cluster quantum state. Some methods can be used to transform Schrödinger-Cat states embedded in the CV quantum cluster state to grid states (such as Gottesman-Kitaev-Preskill states) and enlarge the grid states. In certain embodiments, some of the methods may be used to generate and control non-Gaussian states in macronode cluster quantum states such as cluster states comprising two-mode macronodes.
A method of generating a first cat state embedded in a one-dimensional (1D) canonical cluster state, wherein the 1D canonical cluster state is a continuous variable (CV) quantum cluster state, the method comprising:
The method of claim 0, wherein performing the second homodyne detection comprises performing a π/2 phase-space rotation on the first cat state of the second mode.
A method for generating a squeezed cat state embedded in a one dimensional (1D) canonical cluster state, the method comprising:
18-37. (canceled)
A quantum system for generating a first cat state embedded in a one-dimensional (1D) canonical cluster state, wherein the 1D canonical cluster state is a continuous variable (CV) quantum cluster state of a plurality of modes, and wherein each individual mode of the plurality of modes comprises an optical field, the quantum system comprising:
The quantum system of claim 0, wherein the first and second initial states comprise encoded states.
