(2004) Quantum-enhanced measurements: Beating the standard quantum limit

A possible experiment requiring sensitivities beyond the standard quantum limit
Kuzyk was the first to predict the fundamental physical limits on the nonlinear properties of molecular materials in 2000 and says that by approaching the quantum limit
, the University of Toronto-Carleton team has succeeded where all other researchers have failed.
The combination of moderate resonant frequencies (tens of megahertz) and ultralow temperatures (sub-millikelvin) will enable the quantum limit
of the mechanical oscillator to be reached while also allowing the state of the resonator to be probed and manipulated on experimentally-accessible timescales.
