What is the name of the qubit control device developed by the research group?

The name of the developed qubit control device is "QuEL-1 SE".

How were the fluctuations in the amplitude and phase of microwave signals suppressed?

They were suppressed by introducing individual temperature control mechanisms for analog devices such as Phase-Locked Loops (PLLs) and amplifiers.

What were the confirmed standard deviations of the microwave output's amplitude and phase over a 24-hour measurement?

The standard deviation of amplitude was suppressed to 0.09–0.22% (average 0.15%), and the standard deviation of phase was suppressed to 0.35–0.44° (average 0.39°).

In which scientific journal was this research result published?

The research result was published in the journal named Review of Scientific Instruments.

Which institutions were the researchers of the group associated with?

The researchers in the development and research group were associated with QuEL Inc. and Osaka University's Quantum Information and Quantum Life Science Center (QIQB).
