Abstract: In a general aspect, a quantum computing method is described. In some aspects, a control system in a quantum computing system assigns subsets of qubit devices in a quantum processor to respective cores. The control system identifies boundary qubit devices residing between the cores in the quantum processor and generates control sequences for each respective core. A signal delivery system in communication with the control system and the quantum processor receives control signals to execute the control sequences, and the control signals are applied to the respective cores in the quantum processor.

Abstract: A computer-implemented prediction method, system, and computer program product including detecting an anomaly between at least two images in a social media timeline, analyzing at least one of contextual data and image data associated with the at least two images that cause the anomaly, and predicting an actual time of the at least two images in the social media timeline based on the analyzed at least one of contextual data and image data.

Abstract: A method and system for reserving a time slot to gain access to a resource, such as an attraction, ride, show or event, as may be found in an amusement park. A portable module is used to determine a time when the user is able to access the resource based on reservation requests and throughput, without need for a docking station or continuous communication with a central database of all reservations and queue times.

The system comprises: a plurality of portable access keys, each being provided to one of the users and having an associated variable access parameter; an access barrier, having an open state allowing passage through and a closed state denying access to the resource, and defining an access queue; a sensor that determines an access queue characteristic related to a number of users in the access queue; a controller, which sets an access criterion based on the determined access queue characteristic; and a detector, located at the access barrier and which determines the variable access parameter of a portable access key when it is brought into the vicinity of the detector. The controller sets the access barrier in its open state if the variable access parameter determined by the detector meets the access criterion.

Abstract: The present invention enables personalized recommendations for a user. In a preferred embodiment, a user submits an image of her face along with personal information. The image is analyzed to produce measurements of the user's facial characteristics. A user profile containing the image measurements and personal information is compared to two or more categories of reference data. For each category, one or more recommendations are produced according to the results of the comparison. The top recommendations are chosen according to a prioritization hierarchy and provided to the user.
