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.

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.

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.

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.

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

Three quantum ways to diagonalize 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

IBM Says I Understand Quantum Machine Learning Now

Quantum kernels, variational classifiers, and the honest part: when quantum beats classical machine learning, and when it does not.

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.

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.

Milestones

I Just Earned My Second IBM Quantum Badge, and It Says Advanced

My first IBM Quantum badge said Intermediate and it bent my brain. The second one says Advanced. It is about the algorithms that actually run on today's noisy quantum machines, and I am a self-taught builder who was not supposed to get here.

Milestones

I Just Earned My First IBM Quantum Badge and I Am Not Going Back

There is a type of computer that holds every possible answer at once and only picks one when you force it to look. I found it a few weeks ago. I have not slept well since. First IBM Quantum badge earned. The chapter starts here.
