Broadband Multidimensional Variational Measurement with Non-Symmetric Coupling
Aleksandr A. Movsisian, Albert I. Nazmiev, Andrey B. Matsko +1
A broadband multidimensional variational measurement allows overcoming the Standard Quantum Limit (SQL) of a classical mechanical force detection for a mechanical oscillator. In th…
