Abstract: Aspects of the present disclosure are directed to fabrication methods for analogue quantum systems (AQSs). Further aspects of the present disclosure are directed to methods for solving computational problems using an AQS. Methods for fabricating an AQS include generating a Hamiltonian based on a computational problem, which may be an optimization problem or a simulation problem. Further, the method includes identifying AQS fabrication parameters based on one or more identified measurement methods and the Hamiltonian. Lastly, an AQS can be fabricated based on the identified fabrication parameters. An AQS may be used inter alia to simulate a battery or interfaces.

Abstract: A waste processing system includes a storage tank to collect urine, a dose pump to mix a volume of urine pretreat with a volume of water and dispense the resultant pretreat mixture into the storage tank, and a sensor configured to monitor one or more properties of the pretreat mixture. The sensor is an optical sensor transmitting a light signal through the pretreat mixture. A method of monitoring a flow of a pretreat mixture of a waste processing system includes mixing a volume of urine pretreat with a volume of water at a dose pump defining a pretreat mixture, directing the pretreat mixture along a fluid pathway toward a storage tank, and measuring one or more properties of the pretreat mixture via an optical sensor disposed along the fluid pathway.

Abstract: 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.

Abstract: An apparatus, system, and method for determining a position of a hip prosthesis in a bone of a patient includes determining a set of contact points between a femoral head of a femoral prosthesis and a cup liner of an acetabular cup to be implanted into a patient based on a mechanics model. The mechanics model is indicative of mechanical motion of a hip exhibited during performance of a set of ADL or at corresponding functional positions of the patient. In some embodiments, a mathematical model may be generated based on a plurality of sets of contact points determined using the mechanics model and subsequently used to determine a resultant set of contact points.
