Hardware Technologies and Applications

This lecture covers hardware technologies and applications, focusing on the quantum stack, fidelity to electronic circuit specifications, cryogenic electronics, quantum sensing, interfacing qubits with classical processors, quantum computing stack, cryo-CMOS modeling, cryo-CMOS parameters, mobility over temperature, and modern processes. It delves into choosing technologies like single-electron transistors and superconducting devices, discussing cryo-CMOS characterization, transistor mismatch, low-noise amplifiers, quantum-classical interface, amplifier classification, performance, impedance matching, coaxial cables, and ADC examples. The lecture also explores sampling, quantization, signal-to-noise ratio, effective number of bits, quantization noise, ADC limitations, INL, DNL, ADC architectures, and more.
