This exceeds the " ? = 1 / " N precision limit possible with N non-entangled particles, called the standard quantum limit ( SQL ).

Ultracold atoms are also used in experiments for precision measurements enabled by the low thermal noise and, in some cases, by exploiting quantum mechanics to exceed the standard quantum limit.
13.
Back action has important consequences on the measurement process and is a significant factor in measurements near the quantum limit, such as measurements approaching the Standard Quantum Limit ( SQL ).

It works close to the Quantum limit in measuring the position of individual atoms, and can also be used to move atoms around .-- Solipsist 16 : 46, 15 Sep 2004 ( UTC)

Some easier to check predictions of quantum mechanics are the prediction of negative standard quantum limit using squeezed states of light or the asymmetry of the sidebands in the spectrum of a cavity near the quantum ground state.

Schwab joined the U . S . National Security Agency in 2000 and led a group to study the quantum limits of mechanical structures, during which time he was named as a promising young innovator by Technology Review.
18.
The signal-to-noise ratio for a given light intensity is limited by the standard quantum limit, which is critical for measurements where the probe light intensity is limited in order to avoid damaging the sample.
19.
There is also a quantum limit of decoherence : When the spacing between energy levels of the system is large compared to the frequencies present in the environment, energy eigenstates are einselected nearly independently of the nature of the system-environment coupling.
20.
Usually, " quantum limit " is a general term which refers to " any " restriction on measurement due to quantum effects, while the " standard quantum limit " in any given context refers to a quantum limit which is ubiquitous in that context.
