How to test the “quantumness” of a quantum computer?
... The looming impossibility to predict the behaviour of any big enough quantum processor (adiabatic, gate-based, etc) and even to test it for “quantumness” using classical tools, is the elephant in the room, and it may effectively restrict any further progress. Even taking the optimistic view, that qu ...
