Abstract: A quantum circuit includes: a qubit, a resonant cavity, and a feeder, the resonant cavity being coupled to the qubit, and the feeder being coupled to the qubit. The feeder is configured to feed an initialization signal to the qubit, the initialization signal being a modulation signal used for causing a frequency of the qubit to generate a vibration. The vibration causes an equivalent state exchange to occur between the qubit and the resonant cavity, and an excited state of the qubit is initialized to a ground state by using the resonant cavity.

Abstract: A process of a voice control method with a cloud server and a terminal device. The voice control method includes: a terminal device receiving voice information; the terminal device querying a control instruction corresponding to the voice information from a local voice database; when the control instruction corresponding to the voice information is not queried in the local voice database, the terminal device uploading the voice information to a cloud server; the cloud server parsing the control instruction corresponding to the voice information; when the control instruction corresponding to the voice information is parsed, the cloud server sending the control instruction to the terminal device; and the terminal device receiving the control instruction, and performing a corresponding operation on the basis of control instruction.

Abstract: An easy grease filling machine is disclosed. The grease filling machine comprises a drum cover, a pump body that goes through the drum cover, a grease pressing disc fitted on the pump body. The periphery of the drum cover is configured with a quick locking mechanism compatible to the rim of the grease packing drum and fixed with the drum body, and is matched by a grease pressing disc with its size automatically changeable when it moves up or down inside the drum body based on the different diameters of the drum body from bottom to top. The grease pressing disc comprises a disc body and a grease scraping skirt configured on the outer periphery of the disc body with its cross section shaped like an inverted V.
