Abstract: Disclosed are a synchronous triggering system, a quantum control system and a quantum computer. The synchronous triggering system comprises a central control device, several routing boards and several functional boards. It guarantees the synchronous triggering of the triggering signals by means of a three-stage triggering synchronization system. In the first stage, the central control device provides several sets of triggering signals to corresponding routing boards, and adjusts an initial time point for each set of triggering signals to output so that each chassis receives the triggering signals concurrently. In the second stage, communication lines from each routing board to the several functional boards are of equal length. In the third stage, the triggering signals arrive at several data-processing devices simultaneously after being processed under the AND-operation of an AND-gate chip.
