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…
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…
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…
Two-colour high-purity Einstein-Podolsky-Rosen photonic state
Tulio Brito Brasil, Valeriy Novikov, Hugo Kerdoncuff +2
Entanglement is the backbone of quantum information science and its applications. Entangled states of light are necessary for distributed quantum protocols, quantum sensing and qua…
Cavity-enhanced sum-frequency generation of blue light with near-unity conversion efficiency
Hugo Kerdoncuff, Jesper B. Christensen, Túlio B. Brasil +4
We report on double-resonant highly efficient sum-frequency generation in the blue range. The system consists of a 10-mm-long periodically poled KTP crystal placed in a double-reso…
