To oversimplify a bit, and ignoring some possibly relevant contemporary developments, in quantum mechanics it is necessary to posit the intervention of an «observer» at a certain crucial point of the measurement process.
«We have demonstrated a reconfigurable array of traps for single atoms, where we can prepare up to 50 individual atoms in separate traps deterministically, for future use in quantum information processing, quantum simulations, or precision measurements,» says Vuletic, who is also a member of MIT's Research Laboratory of Electronics.
These technologies exploit quantum mechanics, the physics that dominates the atomic world, to perform disparate tasks such as nanoscale temperature measurement and processing quantum information with lasers.
If the amount of correlation between these measurements doesn't tally with previous Bell tests, it implies a violation of quantum theory, hinting that the measurements at A and B are being controlled by processes outside the purview of standard physics.
Noise also occurs at the quantum scale and can e.g. interfere with the measurements of atomic fountain clocks or with quantum information processing.
