Abstract

The microwave pulse generator 101 consists of a logic circuit 203 that outputs pulse data 213 of a set pulse width and amplitude, a frequency generator 201 that outputs sine waves 211, 212 having the same frequency as the selected quantum bit, a RFDAC 204 that converts pulse data 213 into an analogue signal, modulates it with a sine wave 211 and outputs a signal with the frequency of the sine wave as the center frequency as microwave pulse 111, and a frequency divider 202 that outputs system clock 124 divided by the frequency of sine wave 212. The frequency generator 201 operates at the same frequency as the selected quantum bit except when outputting microwave pulse 111, and the logic circuit 203 operates in synchronization with the system clock 124.
