Abstract | |||||||||||||||
| We propose and discuss two postulates on the nature of errors in highly correlated noisy physical stochastic systems. The first postulate asserts that errors for a pair of substantially correlated elements are themselves substantially correlated. The second postulate asserts that in a noisy system with many highly correlated elements there will be a strong effect of error synchronization. These postulates appear to be damaging for quantum computers. ∗ Research supported in part by an NSF grant, by an ISF Bikura grant, and by a BSF grant. The presentation here is an informal description of some ideas evolved from [23], and it follows my comments in the discussion at Bacon’s “Quantum Pontiff” | |||||||||||||||
