摘要： Systems and methods that address an optimized method to improve systems and methods for handling inequality constraints in mixed binary optimization problems on quantum computers and to solve local optima which significantly improves system performance. Embodiments employ an improved methodology that can optimize parameters, determine an optimal slack variable and optimize variational parameters for fixed slack variables. This procedure allows to move out of local minima, solve an optimization and improve the system performance by providing optimal results. These embodiments also extend to variational hybrid quantum/classical algorithms for gate-based quantum computers.

摘要： Configuring a quantum computing system to determine a solution to an optimization problem includes encoding the optimization problem in an encoding language to produce an encoded optimization model. The encoded optimization model is transformed into a unconstrained model. The encoded optimization model includes an objective function having one or more terms. The one or more terms are converted to one or more Pauli terms. An Ising Hamiltonian is generated using the one or more terms. The Ising Hamiltonian corresponds to the optimization problem. An instruction indicative of the Ising Hamiltonian is provided to the quantum computing system.

摘要： VQE is accelerated by performing receiving a qubit Hamiltonian representing a linear combination of a plurality of Pauli strings. Selecting, among the plurality of Pauli strings, one or more Pauli strings that have less influence than a threshold on an eigenvalue of the qubit Hamiltonian. Grouping, based on joint measurability, the unselected Pauli strings among the plurality of Pauli strings into a plurality of groups of jointly measurable Pauli strings Determining that one or more of the selected one or more Pauli strings is jointly measurable with Pauli strings in one of the plurality of groups And adding one or more of the selected one or more Pauli strings to the one of the plurality of groups.

摘要： Methods and apparatuses for designing quantum circuits include obtaining Pauli strings included in a qubit Hamiltonian. At least some of the strings are grouped, based at least partially on a judgment of whether Pauli strings are observables that are jointly measurable by entangled measurement, at least at some operators. A quantum circuit is designed based on a result obtained from the grouping.

摘要： A computer-implemented method, an automatic pest control monitoring system and computer program product automatically monitor for pests on crops. An autonomous vehicle equipped with a normal camera and at least one alternate camera, simultaneously captures a normal image and a true alternate image containing a same portion of the crops. A composite image is generated using the difference of the captured images. If at least one pest is determined to present by applying an object recognition algorithm to the composite image, reactive measures are automatically deployed. The alternate camera may be an infrared camera or an ultraviolet camera. The composite image is generated by correlating the normal image with the true alternate image, determining the differences between the normal image and the true alternate image, and generating the composite image based on the differences between the normal image and the true alternate image.

摘要： Embodiments relate to a computer implemented information processing system, method and program product for data access. The information processing system includes a data store having a top tier store and at least another tier store with the top tier store including a counter for each entry of a symbol and another tier store including a representative frequency value defined for the another tier store. A sorter is also provided configured to sort the symbol in the top tier store and the another tier stores according to a value generated in the counter for the assessed symbol. The said sorter is also configured to restore entry of the symbol in the top tier store, in response to a symbol having moved from said top tier store to another tier store, by using the representative frequency value defined for said another store to which said symbol was moved.

摘要： Methods and apparatuses for designing quantum circuits include generating a Pauli graph from Pauli strings in a qubit Hamiltonian. Nodes are merged in the Pauli graph, responsive to a determination that some Pauli strings are observables that are jointly measurable by entangled measurement. A quantum circuit based is generated on a merged Pauli graph that results from merging the nodes.
