A 7-bit 1-GSa/s Cryo-CMOS ADC for Spin-Qubit Readout

Quantum computing offers exponential speed-up for problems that are computationally intractable with classical computing. However, quantum processors with thousands to millions of quantum bits (qubits) are needed. Room-temperature electronics are used to control and readout today's qubits operating at cryogenic temperature. As the number of...
