NIST Tightens the Bounds on the Quantum Information 'Speed Limit'

Caption

The size of a quantum computer affects how quickly information can be distributed throughout it. The relation was thought to be logarithmic (blue). Progressively larger systems would need only a little more time. New findings suggest instead a power law relationship (red), meaning that the "speed limit" for quantum information transfer is far slower than previously believed.
