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.

Abstract: One or more systems, devices, and/or methods provided herein relate to a process for in-process radio frequency (RF) signal quality analysis and amplitude adjustment of one or more RF devices. In one or more embodiments, the RF device can comprise a portion of a quantum computing system, such as of readout electronics thereof, and thus amplitude adjustment can be at a waveform generator that generates pulses to affect one or more qubits of a quantum logic circuit of the quantum computing system. Generally, an electronic device can comprise an RF tap connected to an RF signal component of a first RF signal chain, and an analysis component connected to the RF tap, the analysis component configured to convert an RF signal from the RF signal component and to compare a conversion result thereof to an expected power output that is based on historical data for a second RF signal chain.
