Photonics for Quantum sensors

Quantum sensors have been named a top 10 emerging technology by the World Economic Forum in 2020. This is mainly driven by their imminent application potential and the ability to open up qualitatively new sensing areas, such as sensing into the ground, or seeing the brain at work. We are now just one step away from commercial breakthrough applications in civil engineering and clinical trials. With this success, the next step will be to develop integrated photonics components to open up mass markets in water, navigation and gaming. I will provide an overview of the working principle of an atomic quantum sensor and lay out the parameter needs for photonic integration.
