Everything is already a quantum computer…

Everything is already a quantum computer — including conventional computers. They are quantum machines intentionally constrained to operate only through deterministic steps. Every atom shares information through time-dependent entanglement, the same principle a quantum logic gate uses. Classical computers are useful because this constraint filters out the wild, non-deterministic noise of the quantum world — even interference from background radiation. Their reliability comes from this engineered limitation, a deliberate narrowing of the universe’s deeper computational nature. – Rico Roho
