Quantum Computers Just Revealed Something "HORRIBLE" About Reality

A deep exploration of quantum computing through the lens of theoretical physics, covering David Deutsch's foundational 1985 paper, Hugh Everett's many-worlds interpretation, and Google's 2019 quantum supremacy demonstration with Sycamore. The piece examines how quantum computers may require parallel universes to function, explains superposition, decoherence, and quantum interference as computational mechanisms, and discusses Shor's algorithm's threat to modern encryption. It also covers quantum entanglement (validated by Aspect's 1982 Bell test experiments), quantum teleportation, the holographic principle, topological qubits (Microsoft's 2024 Majorana fermion announcement), and the fundamental problem of verifying quantum computations classically. The narrative weaves together the stories of physicists like Everett, Wheeler, Hawking, and Feynman to argue that quantum computers may be operating on the informational substrate of reality itself.
