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…
Deterministic coupling of ultracold atomic lattice to a suspended photonic waveguide
J. T. Hansen, F. Gargiulo, J. B. Mathiassen +3
The deterministic control of light-matter interactions at the level of single particles and on subwavelength scales is central to quantum optics and hybrid integrated quantum techn…
Coherent phase control of two-color continuous variable entangled light
Andrea Grimaldi, Valeriy Novikov, Túlio Brito Brasil +1
A continuous variable Einstein-Podolsky-Rosen (EPR) state is a resource for secure quantum communication and distributed quantum sensing. Here we present a technique for coherent c…
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…
