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 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…
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…
Spin-alignment noise in atomic vapor
A. A. Fomin, M. Yu. Petrov, G. G. Kozlov +4
In the conventional spin noise spectroscopy, the probe laser light monitors fluctuations of the spin orientation of a paramagnet revealed as fluctuations of its gyrotropy, i.e., ci…
Detection of low-conductivity objects using eddy current measurements with an optical magnetometer
Kasper Jensen, Michael Zugenmaier, Jens Arnbak +3
Detection and imaging of an electrically conductive object at a distance can be achieved by inducing eddy currents in it and measuring the associated magnetic field. We have detect…
Magnetocardiography on an isolated animal heart with a room-temperature optically pumped magnetometer
Kasper Jensen, Mark Alexander Skarsfeldt, Hans C. Stærkind +5
Optically pumped magnetometers are becoming a promising alternative to cryogenically-cooled superconducting magnetometers for detecting and imaging biomagnetic fields. Magnetic fie…
