Patent number: 11972323Abstract: An apparatus includes a light source to provide a plurality of input optical modes in a squeezed state. The apparatus also includes a network of interconnected reconfigurable beam splitters (RBSs) configured to perform a unitary transformation of the plurality of input optical modes to generate a plurality of output optical modes. An array of photon counting detectors is in optical communication with the network of interconnected RBSs and configured to measure the number of photons in each mode of the plurality of the output optical modes after the unitary transformation. The apparatus also includes a controller operatively coupled to the light source and the network of interconnected RBSs. The controller is configured to control at least one of the squeezing factor of the squeezed state of light, the angle of the unitary transformation, or the phase of the unitary transformation.Type: GrantFiled: January 27, 2023Date of Patent: April 30, 2024Assignee: Xanadu Quantum Technologies Inc.Inventors: Kamil Bradler, Daiqin Su, Nathan Killoran, Maria Schuld, Zachary Vernon, Lukas Helt, Blair Morrison, Dylan Mahler

Publication number: 20240053615Abstract: An apparatus includes an optical circuit having at least one reconfigurable beamsplitter and is configured to receive a plurality of input optical modes in a Gaussian state and generate a plurality of output optical modes. The apparatus also includes at least one detector optically coupled with the optical circuit and configured to perform a non-Gaussian measurement of a first output optical mode from the plurality of output optical modes. The non-Gaussian measurement of the first output optical mode is configured to cause a second output optical mode from the plurality of output optical modes to be in a first non-Gaussian state. The apparatus also includes a controller operatively coupled to the optical circuit and configured to change a setting of the at least one reconfigurable beamsplitter to cause the second output optical mode from the plurality of output optical modes to be in a second non-Gaussian state.Type: ApplicationFiled: October 9, 2023Publication date: February 15, 2024Applicant: Xanadu Quantum Technologies Inc.Inventors: Krishnakumar SABAPATHY, Haoyu QI, Joshua Abe IZAAC, Christian WEEDBROOK, Daiqin SU, Casey MYERS
