Quantum Computing
One builder learning quantum computing from the ground up, in public. The math, the code, and the unglamorous reality, one verified step after another.

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.

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.

14:44 Quantum Computing The Python you actually need for quantum computing
Dictionaries for counts, just enough OOP to read Qiskit, and NumPy as the bridge. The thin slice that matters, nothing else.

13:16 Quantum Computing A qubit is not a coin under a cup
The superposition myth, taken apart with math you can run. Not a hidden answer waiting to be read, but something stranger and far more precise.
