Quantum Physics for Software Developers
summary
Uses Q# code and a local simulator to recreate beam-splitter and interferometer experiments, showing a single qubit with H gate gives 50/50 detector outcomes, two H’s produce 1000 zeros (self‑interference), and inserting a mid‑measurement yields a 50/50 split. Models Schrödinger’s cat with 3 qubits (atom+2 cat) and adds 5 environment qubits to show rapid decoherence. Demonstrates spin measurements where X vs Z bases destroy information, implements entanglement with CNOT and verifies Bell‑style correlations and teleportation (protocol runs succeed).
