*Nature* thinks this paper could “rock quantum theory to its core”: Excerpt:

“On a related, but more abstract note, the quantum state has the striking property of being an exponentially complicated object. Specifically, the number of real parameters needed to specify a quantum state is exponential in the number of systems n. This has a consequence for classical simulation of quantum systems. If a simulation is constrained by our assumptions – that is, if it must store in memory a state for a quantum system, with independent preparations assigned uncorrelated states – then it will need an amount of memory which is exponential in the number of quantum systems.” – Matthew F. Pusey, Jonathan Barrett, Terry Rudolph, “The quantum state cannot be interpreted statistically”

Recalling the *New Scientist* editor who, acknowledging that the riddle of free will is unsolved, is convinced that there is no free will, due to the compete derminism of the universe: One asks, How could he know that, if it would be exponentially difficult to even specify a quantum system (which is not determinist anyway)?
