Abstract: A quantum state classifier includes a reservoir computing circuit for post-processing a quantum bit to obtain a readout signal, and a readout circuit, coupled to the reservoir computing circuit, for discriminating a quantum state of the quantum bit from the readout signal from among multiple possible quantum states. The readout circuit is trained in a calibration process respectively activated by a specific one of each of the multiple quantum states such that weights within the linear readout circuit are updated by minibatch learning for each of multiple measurement sequences of the calibration process. The readout circuit generates a binary output after the multiple measurement sequences in a post-calibration classification process for a test quantum bit. The quantum state classifier further includes a controller, coupled to the readout circuit, selectively triggerable to output a control pulse responsive to the quantum state of the test quantum bit indicated by the binary output.

Abstract: Within a housing portion in which a recessed portion is formed, a circuit board is arranged on the bottom surface of the recessed portion, through a first connecting member. An acceleration sensor is stacked on the circuit board, through a second connecting member. Hence, sections that function as three or more springs, i.e., an anti-vibration portion, the first connecting member, and the second connecting member, are situated between an angular velocity sensor and the acceleration sensor. For this reason, transmission of vibration of the vibrating element in the angular velocity sensor to the acceleration sensor can be restricted, and reduction in the detection accuracy of the acceleration sensor can be restricted.
