Abstract: In a general aspect, a quantum program is automatically synthesized. In some implementations, artificial intelligence systems are used to generate a quantum program to run on a quantum computer. In some aspects, quantum processor output data are generated by a quantum resource executing an initial version of a quantum program, and quantum state information is computed from the quantum processor output data. Neural network input data, which include the quantum state information and a representation of a problem to be solved by the quantum program, are provided to a neural network. Neural network output data are generated by the neural network processing the neural network input data. A quantum logic gate is selected based on the neural network output data. An updated version of the quantum program that includes the selected quantum logic gate is generated.

Abstract: Processes of extracting mineral deposits in ore include treating a saline source, e.g., seawater, to reduce a concentration of one or more multivalent ions (e.g., Ca2+, Mg2+, SO42?) dissolved in the saline source by passing the seawater through one or more nanofilters to produce treated saline water while maintain a certain concentration of dissolved monovalent ions (e.g., (Na+, K+ and Cl?) in the treated saline water. The treated saline water can be used in an operation to extract minerals from ore such as in a flotation operation to extract minerals from ore, or to consolidate tailings generated from an extraction of minerals from ore, or both.
