I emulated 24 quantum gates (Hadamard, Bell, QFT, Grover, CNOT, teleportation) using only an OLED phone and a pocket mirror — optical MatVec as the primitive

**The primitive: optical MatVec** Phone screen-down over a flat mirror. Front camera reads reflected light. One exposure = one matrix-vector multiply: Q = η · T · Σᵢ wᵢxᵢ This is a dot product computed by physics — no CPU multiply-accumulate. **24 quantum gate experiments built on this:** - Hadamard, Pauli X/Y/Z, Phase gates - CNOT, Toffoli, SWAP - Bell state preparation & measurement - Deutsch-Jozsa algorithm - Grover's search - QFT (Quantum Fourier Transform) - Quantum teleportation protocol - True QRNG via shot noise — passes NIST statistical tests These are classical emulations of quantum gate unitary matrices via optical MatVec — useful for education, algorithm prototyping, and analog verification. **Measured results:** - Optical channel linearity: R² ≈ 1.0 - Dynamic range with mirror vs without: ×4000 - MatVec correlation vs CPU: 0.998 **Total: 101 experiments** across Neural Networks (22), Wave Physics (29), Quantum Gates (24), Math Algorithms (26) Repo + 3-command setup: https://github.com/infosave2007/svetoch 6 Zenodo papers with DOI: https://doi.org/10.5281/zenodo.20729632 Reference device: Xiaomi 12 Lite.
