Measurement, Decoherence and What the Bloch Sphere Cannot Show You
The Bloch sphere is a map with edges. This final part covers what measurement does to the arrow, why real qubits drift inside the ball, and why an entangled qubit has no arrow at all.

Rx, Ry and Rz: Reaching Any Point on the Bloch Sphere
Give a rotation a dial instead of a fixed angle and you can steer a qubit anywhere on the Bloch sphere with two gates. This is the Euler decomposition, and it is what your transpiler does to every circuit you run.
Read tutorial → - Turing machines Concepts
Turing Machines, Computability, and What Quantum Computing Actually Changes
A quantum computer computes exactly the same set of functions as a Turing machine, no more and no fewer. It cannot solve the halting problem. What it changes is efficiency, not computability, and this tutorial draws the line precisely.

Hadamard, S and T on the Bloch Sphere
The Hadamard gate is a half-turn about a diagonal axis, and S and T are partial twists about the vertical one. Seen on a live Bloch sphere, the H, S and T gates stop being matrices and start being furniture-moving.
