Title:
QUANTUM BIT DRIVE SIGNAL GENERATION APPARATUS, GENERATION METHOD, AND QUANTUM COMPUTER
Document Type and Number:
WIPO Patent Application WO/2023/072192
Kind Code:
A1
Abstract:
A quantum bit drive signal generation apparatus, comprising: a microwave source module, used to output multiple microwave signals at different frequencies; a control module connected to the microwave source module, used to determine a phase coherence point on the basis of the frequency or phase of two microwave signals, and output a trigger signal according to the phase coherence point, the phase coherence point being a moment at which a phase difference between a first microwave signal and a second microwave signal is consistent; a waveform output module, used to output intermediate-frequency signals corresponding to multiple quantum bit drive signals in response to the trigger signal; and a signal processing module connected to the microwave source module and the waveform output module, used to output multiple quantum bit drive signals on the basis of the multiple intermediate-frequency signals and multiple microwave signals.
