1. 01From an abstract qubit to a deviceSuperconducting circuits, trapped ions, neutral atoms and photons: what each does well.12 min
2. 02Classical Compiler vs. Quantum TranspilerWhat happens when you press Compile, explained by comparing it with how C or Python code becomes machine instructions.12 min
3. 03Transpilation and basis gatesWhat the compiler does in four stages, what the optimisation levels change, and how to read the Compile preview.12 min
4. 04Circuit Identities & Gate CancellationThe handful of rewrite rules an optimiser uses, and a bloated circuit you can watch shrink from level 0 to level 3.12 min
5. 05Topology and SWAP costCoupling maps, the heavy-hex lattice, and how to lay out a circuit so the router adds nothing.10 min
6. 06Running on IBM QuantumToken, instance, queue, minutes: a checklist for a first real-hardware job and how to read the result.10 min
