# FQC – The “Fun Quantum Critic” ## ⚡️ Why we are skeptical about quantum computing The author of this project demonstrates that the hype surrounding quantum computers vastly exceeds their practical, near‑term capabilities. A detailed critique through actual **deterministic (and no‑information‑exchange) simulation of quantum entanglement** is at . It shows that quantum effects can be modeled fully and deterministically – **no magic**. It uses **pulse‑width modulation** – the key trick quantum theory makes you believe in is that there is no communication happening, while in reality a *coincidence detector* (modeled in *q*, as well as its equivalents in more complex experiments) is hiddenly designed to be the communication point in every quantum experiment. > Moreover: the `qubits` we currently can build are **noisy, expensive and nowhere near** the scale required for the algorithms that are often advertised. Relying on “quantum supremacy” for real‑world quantitative research is, at best, a gamble. A quantum computer without noise (or with noise minimized) would still be **worse than an analog computer (without noise)** in its performance. ### 🔬 Why the reproduction of CHSH‑type experiment on **q.doomsdayexplorer.online** is not proof of quantum "absolute non-determinism" entanglement 1. **Classic deterministic model** – The simulation runs on an ordinary (non‑quantum) computer using only classical arithmetic. No quantum superposition or wave‑function collapse is ever invoked. 2. **Coincidence‑detector post‑selection** – The detector does *not* exchange any data between the two measurement stations. It simply **collects raw outcomes**, then applies a **comparison/filtering rule** (the “coincidence window”). This rule **biases the joint statistics**, producing values that look like a CHSH violation even though the underlying data are completely independent. 3. **No‑communication proof** – Because the algorithm never sends a bit from one side to the other, the observed correlation cannot be attributed to a non‑local quantum link. The apparent “entanglement” is a statistical artifact of the **post‑selection procedure**, not a physical phenomenon. 4. **Implication** – If a **trivial deterministic model** can replicate the published CHSH results, the claim that such experiments *prove* quantum supremacy or genuine entanglement loses its evidential weight. > **Bottom line:** the “magic” behind quantum entanglement, as presented in many popular demonstrations, can be reproduced (and thus refuted) with a simple classical simulation that carefully models the coincidence detector.
