In January 2025, the engineers at PsiQuantum achieved a milestone that had eluded the field for decades: a manufacturable, fault-tolerant photonic quantum computing chipset. But buried in their breakthrough was a fundamental physics problem: you cannot create a photon with absolute certainty, meaning the machine had to be built from inherently unreliable parts. To make it work, they devised a brilliant architecture involving probabilistic generation, heralded verification, and massive multiplexing to turn stochastic noise into reliable computation.

But they weren't the first to invent it. As we reveal in this episode of Relatively Human, that exact architectural strategy was deployed two billion years ago inside your own cells. We explore the eerie structural convergence between the world’s newest quantum computer and the mitochond ...
