摘要： A method includes receiving initial quantum states of light or a representation thereof at an optical circuit, from a set of sources. The initial quantum states of light include squeezed states of light, approximate squeezed cat states of light, and/or approximate states of light having at least 3 associated peaks. The optical circuit includes at least one programmable beamsplitter and at least one homodyne detector. The method also includes receiving, at the optical circuit, a signal to cause programming of the at least one programmable beamsplitter and the at least one homodyne detector. The programming is based on at the initial quantum states of light, a measurement of the at least one homodyne detector, and/or a user input. The method also includes generating a plurality of Gottesman-Kitaev-Preskill (GKP) quantum states of light by propagating the initial quantum states of light through the programmed beamsplitter(s) and using the programmed homodyne detector(s).
