Quantum computers suffer from clumsy signals, like an orchestra without a conductor. But the engineering method iLQR turns chaos into a symphony: smooth pulses reduce errors to record low levels. This could make quantum computing as reliable as your smartphone.

🎯 Entropy — a concept from physics — today helps assess quantum noise. It's like coming up with a formula for scattered socks: the more ways they can be messy, the higher the entropy.

🎬 In the series 'The Expanse,' quantum computers use advanced algorithms — and methods like iLQR are turning such science fiction into reality.
