This lecture covers the fundamentals of quantum computing, including qubit realization, control, scalable quantum computers, quantum communication, sensing, and metrology. It reviews Larmor and Rabi oscillations, qubit state control on Bloch's sphere, reading spin qubit states, DC and RF readout techniques, qubit controller specifications, Horse Ridge initial and final architectures, optimizing phase/amplitude resolution, instruction set memory, power breakdown, and measurement setup. It also discusses self-heating effects, power consumption breakdown, single-tone spectrum, pulse shaping, qubit device in experiments, Rabi experiments, multiple qubit manipulations, randomized benchmarking, simultaneous Rabi oscillations, 2-qubit gate, comparison table, and synthesis problems in quantum computing.
