➀ CEA-Leti and Quobly have developed a novel solution using FD-SOI CMOS technology for simultaneous microsecond readouts of tens of quantum devices.
➁ The solution reduces readout power consumption by 10x and footprint by 2x.
➂ The proposed readout circuit based on a capacitive-feedback transimpedance amplifier (CTIA) achieves an 18.5μW/qubit power consumption.
