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 state, or one qubit of an entangled pair, does not. Density matrices, quantum channels, and what they show that vectors miss.

09:38 Milestones Three quantum ways to diagonalise a giant matrix
A surprising number of hard problems are one eigenvalue problem on a matrix too big to build. Variational, Krylov, sample based, compared.

19:03 Milestones IBM says I understand quantum machine learning now
Quantum kernels, variational classifiers, and the honest part: what it would take for quantum to beat classical machine learning, and why it has not yet.
