Quantum computing, built from qubits
The math I skipped. The algorithms. The parts that bent my brain. I spend my days building systems where one wrong assumption quietly breaks everything downstream. I come to quantum the same way: I run everything before I believe it.

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 died 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.

17:51 Milestones My IBM Quantum node for n8n is now live
Quantum and automation are my two threads. This node is where they meet. It is verified on n8n Cloud now, and installs straight from the canvas.

05:20 Quantum Computing How I use AI as a tutor without letting it lie to me
The best study partner I have ever had is also the most confident liar I have met. The prompts and checks that keep it honest.

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.

15:38 Milestones The density matrix: what the state vector misses
A pure state fits in a vector. A noisy or entangled one does not. Density matrices, quantum channels, and what they show that vectors miss
