Quantum Physics for Software Developers
summary
Code reproduces beam-splitter and Mach–Zehnder results in Q#: a single qubit with an H gate and measurement yields 1,000 runs ≈ 50/50, two H gates yield 1,000 runs all zeros (interference), inserting a mid-measurement collapses superposition and restores randomness. Stern–Gerlach behavior and Heisenberg uncertainty appear when measuring in X then Z. Bell‑test correlations beat classical limits; entanglement creates nonseparable 4D states and enables teleportation via entanglement. Largest lab superposition cited: 7,000 atoms, 12 ms.
