Abstract: A quantum computation controller according to one embodiment of the present disclosure has a control signal generator, an observation unit that receives an observation signal indicating the state of each qubit, and a qubit module. The qubit module has a qubit substrate on which a plurality of qubits are arranged, a control circuit, an observation circuit, and a signal processing circuit. The plurality of qubits are grouped into a plurality of groups consisting of a plurality of qubits having the same positional relationship between each qubit and are arranged on the qubit substrate. The control signal generator generates a control signal for performing one or more types of spatially uniform first operation which is an operation for a qubit on the qubit substrate and for performing one or more types of spatially non-uniform second operation, which is an operation for a qubit on the qubit substrate, performed less frequently than the first operation and an instruction signal for causing the control circuit to perform control of the first and the second operations. The control circuit splits the control signal into groups and controls the sending of the control signal to each qubit on the qubit substrate according to the instruction signal. The observation circuit observes the state of each qubit on which the first operation or the second operation has been performed. The signal processing circuit sends the observation signal of each qubit to the observation circuit.
