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…

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…

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…

Acoustic frequency atomic spin oscillator in the quantum regime

Jun Jia, Valeriy Novikov, Tulio Brito Brasil +3

We experimentally demonstrate quantum behavior of a macroscopic atomic spin oscillator in the acoustic frequency range. Quantum back-action of the spin measurement, ponderomotive s…

Squeezed light from an oscillator measured at the rate of oscillation

Christian Bærentsen, Sergey A. Fedorov, Christoffer Østfeldt +3

Continuous measurements of the position of an oscillator become projective on position eigenstates when the measurements are made faster than the coherent evolution. We evidence an…
