- Abstract: Magnetic induction tomography (MIT) is a sensing protocol, exploring
conductive objects via their response to radio-frequency magnetic fields. MIT
is used in nondestructive testing ranging from geophysics to medical
applications. Atomic magnetometers, employed as MIT sensors, allow for
significant improvement of the MIT sensitivity and for exploring its quantum
limits. Here we report entanglement-enhanced MIT with an atomic magnetometer
used as the sensing element. We generate an entangled and spin-squeezed state
of atoms of the sensor by stroboscopic quantum non-demolition measurement. We
then utilize this spin state to demonstrate the improvement of one dimensional
MIT sensitivity beyond the standard quantum limit.

- Is animal magnetoreception quantum? A perspective from the energy resolution limit [0.0]
A large number of magnetic sensors, like superconducting quantum interference devices, were shown to satisfy the energy resolution limit.
This limit states that the magnetic sensitivity of the sensor, when translated into a product of energy with time, is bounded below by Planck's constant.
Here we explore biological magnetometers, in particular three magnetoreception mechanisms thought to underly animals' geomagnetic field sensing.

Microwave or radio-frequency driving poses a significant limitation for miniaturization, energy-efficiency and non-invasiveness of quantum sensors.
We overcome this limitation by demonstrating a purely optical approach to coherent quantum sensing.
Our results pave the way for highly compact quantum sensors to be employed for magnetometry or gyroscopy applications.
