A quantum measurement and control system and a quantum computer are disclosed. The quantum measurement and control system includes: a first signal output module (2) configured to generate waveforms to be processed corresponding to qubits connected with a qubit measurement bus based on a preset time sequence and process the waveforms to be processed into one synthesized waveform, and output a qubit reading signal corresponding to the synthesized waveform to the qubit measurement bus, wherein a waveform to be processed for a qubit includes a measurement waveform when the qubit needs to be measured or an empty waveform when the qubit does not need to be measured; a signal acquisition module (3) configured to acquire and process a qubit reading feedback signal output by the qubit measurement bus based on the preset time sequence, to obtain quantum state information of each qubit which needs to be measured; and a control module (4) configured to output a synchronous trigger signal as a start time of the preset time sequence to the first signal output module and the signal acquisition module. The utilization rate of qubits on the quantum chip can be improved.
