Quantum Hardware
From physical qubits to reliable quantum processors
How does a physical device realize the states, gates, and measurements used by a quantum algorithm? Develop energy levels, control, coupling, readout, and noise through concrete examples, then examine the principal hardware platforms, their infrastructure, and their scaling constraints.

The Quantum Computing course or equivalent familiarity with qubits, gates, and measurement. Atomic, optical, and circuit physics are introduced through the devices that require them.
19 of 19 chapters contain draft lessons with worked examples and solved problems. These are teaching manuscripts in development; advanced results are stated with their assumptions and sources where a full proof lies beyond the course.
Each platform is examined through the same questions: what stores a qubit, how is it prepared, controlled, coupled, and measured, what causes errors, and what limits scaling? Numerical examples are illustrative models, not claims about a current commercial processor.
