Abstract: An example touch display apparatus includes a touch display panel including one or more touch areas. Each touch area can include touch structures, where each touch structure includes first touch electrodes arranged along a first direction and second touch electrodes arranged along a second direction. Each first touch electrode can include first electrode blocks arranged along the second direction. Each second touch electrode can include second electrode blocks arranged along the first direction. The display apparatus can further include at least one touch driver chip, where one touch driver chip is electrically connected to a touch signal line connected to touch structures in one touch area.

Abstract: This application discloses quantum key distribution methods and devices, and storage media. In an implementation, an ith node generates, based on a determined first quantum key corresponding to the ith node on a target routing path and a determined second quantum key corresponding to the ith node on the target routing path, a third quantum key corresponding to the ith node on the target routing path, and sends the third quantum key corresponding to the ith node on the target routing path to a destination node on the target routing path, or encrypts a received first ciphertext by using the third quantum key corresponding to the ith node on the target routing path, and sends an obtained second ciphertext corresponding to the ith node to an (i+1)th node on the target routing path.

Abstract: This application provide quantum key distribution methods, devices, and storage media. In an implementation, a method comprises: determining, based on a first mapping, a first quantum key of N first quantum keys corresponding to an ith node on a target routing path; determining, based on a second mapping, a second quantum key of N second quantum keys corresponding to the ith node; and generating, by the ith node based on the first quantum key corresponding to the ith node and the second quantum key corresponding to the ith node, a third quantum key corresponding to the ith node on the target routing path.
