Abstract: This application discloses a quantum gate optimization method performed by a computer device. The method includes: obtaining an initialized control external field corresponding to a quantum gate; applying the control external field to a quantum bit (qubit) corresponding to the quantum gate, and acquiring actual measurement data of the quantum gate, the actual measurement data being used for reflecting an actual characteristic of the quantum gate; calculating a gradient corresponding to the control external field based on the actual measurement data and ideal data, the ideal data being used for reflecting an ideal characteristic of the quantum gate; and updating the control external field according to the gradient to obtain an updated control external field, the updated control external field being applied to the qubit corresponding to the quantum gate to optimize precision of the quantum gate. The method is a closed-loop optimization solution driven and implemented by data feedback.

Abstract: A method for positioning an IP location and a server are provided. The method comprises: obtaining location data of mobile terminals used by a plurality of users in a preset period to generate a first geographic location data set; pre-processing the first geographic location data set to obtain a second geographic location data set; obtaining a first selected location and a second selected location of each user according to the second geographic location data set; obtaining IP address data corresponding to fixed terminals used by the plurality of users to generate an IP address data set; pre-processing the IP address data set to obtain a plurality of IP sections; obtaining a plurality of first selected locations and second selected locations corresponding to the users of each IP section; and clustering the plurality of first selected locations and second selected locations to obtain the IP location of the IP section.
