14:11 Quantum Computing The version trap that cost me an evening (Qiskit 2.x)
execute() is gone, Aer moved out, and the tutorials never got the memo. What is dead in Qiskit 2.x and the modern pattern that replaced it.

22:33 Quantum Computing Measurement is not magic: the Born rule by hand
Why a quantum result is a probability: amplitude squared, worked on paper and checked in NumPy, one basis at a time.

06:26 Milestones Running quantum circuits on real IBM hardware from n8n
I built an open source n8n node for IBM Quantum and ran a Bell state on a real 156-qubit processor. The full loop, the transpilation gotcha, and why n8n.
