Title:
QUANTUM MEASUREMENT AND CONTROL SYSTEM AND QUANTUM COMPUTER
Document Type and Number:
WIPO Patent Application WO/2023/030101
Kind Code:
A1
Abstract:
A quantum measurement and control system and a quantum computer. The quantum measurement and control system comprises: a first signal output module (2), which is used for generating, on the basis of a preset time sequence, waveforms to be processed of quantum bits that are correspondingly connected to a quantum bit measurement bus, and then processing same to form a synthesized waveform, and for outputting, to the quantum bit measurement bus, a quantum bit reading signal corresponding to the synthesized waveform, wherein the waveforms to be processed comprise measurement waveforms of when the quantum bits need to be measured or empty waveforms of when the quantum bits do not need to be measured; a signal acquisition module (3), which is used for acquiring and processing, on the basis of the preset time sequence, a quantum bit reading feedback signal that is output by the quantum bit measurement bus, so as to obtain quantum state information corresponding to each quantum bit that needs to be measured; and a control module (4), which is used for outputting, to the first signal output module and the signal acquisition module, a synchronous trigger signal that is taken as a starting time of the preset time sequence. The utilization rate of quantum bits on a quantum chip can be increased.
