Abstract: A quantum computation controller according to one embodiment 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 qubits are grouped into a plurality of groups. The control signal generator generates a control signal for performing a first operation, a control signal for performing a second operation and an instruction signal. The control circuit splits the control signal into groups and controls the sending of the control 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.

Abstract: A superconducting complex quantum computing circuit includes a circuit substrate in which a wiring pattern of a circuit element including quantum bits and measurement electrodes, and ground patterns are formed, and through-electrodes connecting the ground pattern formed on a first surface of the substrate surface and the ground pattern formed on a second surface; a first ground electrode including a first contact portion in contact with the ground patterns, and a first non-contact portion having a shape corresponding to a shape of the wiring pattern; a second ground electrode including a second contact portion in contact with the ground pattern; a control signal line provided with a contact spring pin at a tip; and a pressing member that presses the first ground electrode against the first surface of the circuit substrate or presses the second ground electrode against the second surface of the circuit substrate.
