**(ScienceAlert)** Scientists have made a discovery about how optimal quantum computation might be achieved – and gravity may be the key. The geometric rules for finding the shortest distance between two points on a curved surface, with regard to gravity in general relativity, could also find the most efficient way to process information in a quantum computer.

The researchers behind the new study say they could unlock the fastest possible calculations in one particular branch of quantum computing, conformal field theory.

The new study builds on previous work looking at the link between quantum computing and geometry, but goes further by settling on a universal description of complexity – that means previously undiscovered connections between complexity and gravity begin to show up.
