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

Patent number: 11747132Abstract: A method includes receiving a representation of an N-mode interferometer and a representation of at least one imperfection associated with the N-mode interferometer at a processor, N being a positive integer value. The processor identifies multiple two-mode interferometers and multiple phases based on the representation of the N-mode interferometer and the representation of the at least one imperfection. The multiple two-mode interferometers and the multiple phases are configured to apply a unitary transformation to an input signal. The method also includes sending a signal to cause at least one of storage or display of a representation of the multiple two-mode interferometers and a representation of the multiple phases.Type: GrantFiled: December 17, 2021Date of Patent: September 5, 2023Assignee: Xanadu Quantum Technologies Inc.Inventors: Ish Dhand, Shreya Prasanna Kumar, Dylan Mahler, Blair Morrison, Lukas Helt, Leonhard Neuhaus
