1. 01Measuring in the middleWhat changes when a measurement is followed by more gates, and why statevector tools step aside.10 min
2. 02if / else on a measured bitFeed-forward: apply a correction only when a bit says so. Build it from the palette and write it in both languages.12 min
3. 03Loops and switchRepeat until success with while, unroll constant for loops, pick a branch with switch.12 min
4. 04Teleportation with feed-forwardThe protocol that needs dynamic circuits: two classical bits move one qubit of state.14 min
