For the past six years, Los Alamos National Laboratory has led the world in trying to understand one of the most frustrating barriers that faces variational quantum computing: the barren plateau.

Ask a bunch of physicists to explain a quantum experiment and you’re unlikely to get the same description twice. Everyone agrees that the mathematical framework of quantum mechanics is peerless at ...

Everyone has their favourite example of a trick that reliably gets a certain job done, even if they don’t really understand why. Back in the day, it might have been slapping the top of your television ...
