Entanglement-enhanced optical magnetometry beyond the standard quantum limit
Jun Jia, Túlio Brito Brasil, Maimouna Bocoum +6
Optical atomic magnetometry is a powerful tool for continuous sensing applications, yet, in the absence of quantum correlations, its sensitivity is limited by the standard quantum…
Hybrid SU(1,1) interferometry in optomechanics
Chao Meng, Emil Zeuthen, Polina R. Sharapova
In non-degenerate SU(1,1) interferometers, beam splitters are replaced by two-mode squeezers, enabling sub-shot-noise sensitivity without input squeezing and robustness to detectio…
Hybrid quantum network for sensing in the acoustic frequency range
Valeriy Novikov, Jun Jia, Túlio Brito Brasil +6
Ultimate limits for sensing of fields and forces are set by the quantum noise of a sensor. Entanglement allows for suppression of such noise and for achieving sensitivity beyond st…
Simultaneous ponderomotive squeezing of light by two mechanical modes in an optomechanical system
Peyman Malekzadeh, Emil Zeuthen, Eric Langman +2
We experimentally demonstrate a source of squeezed light featuring simultaneous ponderomotive squeezing from two mechanical modes of an optomechanical system. We use ultra-coherent…
