Abstract: A method, system and computer program product for improving discernment between qubit states in superconducting quantum computers. Channels are calibrated to train the kernel to contain the correct calibration data (“kernel states”). After calibrating a channel, testing is performed in which quantum operations are performed on qubits at the same time in adjacent channels, including the recently calibrated channel, to determine if the kernel response differs from the expected kernel response, where the expected kernel response is based on the kernel states of the trained kernel of the recently calibrated channel, beyond a threshold value. If such a situation occurs, then the phase of the signal for the recently calibrated channel is shifted and the process of recalibrating the channel (using the phase shifted signal) and testing is repeated until the difference between the kernel response and the expected kernel response is not beyond the threshold value.

The microfluidic device is caused to dispense etchant that removes the defect of the circuit, where a flow of the etchant is controlled to access the portion of the circuit having the defect to thereby etch away the defect, the flow of the etchant being obstructed from accessing other portions of the circuit. The microfluidic device is used to extract the etchant from the portion of the circuit such that the etchant avoids contact with the other portions of the circuit. The microfluidic device is removed from the circuit.
