Why Quantum Computers Are Faster — the Answer Isn't Parallelism

A qubit isn't a bit with randomness — it's a rotating arrow on a sphere. A quantum gate is a rotation of that arrow. A quantum algorithm is one global transformation that reshapes the whole solution landscape. With Qiskit code, a Bloch-sphere walkthrough, Grover in four bar-chart snapshots, and an honest 2026 status check.
