CEA and Quobly Demonstrate 18.5μW/qubit Cryo-CMOS Readout with QAM Multiplexing for Spin Qubits0 (0)
CEA-Leti, in collaboration with Quobly, CEA-List, and CEA-Irig, has unveiled a cryo-CMOS charge-readout IC capable of simultaneous microsecond readouts for multiple qubits, achieving a record-low power consumption of 18.5μW per qubit. Presented at ISSCC 2025, the solution leverages FD-SOI CMOS […]
