Many sensing tasks enjoy uniquely quantum features making quantum devices very appealing for fundamental research and technological applications.
In this talk I will describe three features of this sort which we recently used in order to enhance sensing capabilities:
1. Wave-particle duality allowing beneficial atomic wavepacket shaping .
2. Set-coherence giving rise to amplified quantum metrology, including robustness to noise and decoherence [2-4].
3. Continuous variables entanglement/squeezing leading to phase sensitivity beyond the shot-noise limit [5-7].
