Abstract: Quantum sensing leverages the principles of quantum mechanics to provide ``quantum-enhanced'' measurement sensitivity, thereby amplifying our ability to observe interesting physical phenomena. It employs a rich arsenal of techniques, including squeezing, photon counting, entanglement assistance, and distributed quantum sensing to achieve unprecedented sensitivity. Quantum sensor technologies span a wide range of physical systems — ranging from cryogenically cooled microwave resonators to mechanical membranes coupled to optical light — with far-reaching applications in, e.g., the fields of fundamental physics, where squeezing has been utilized to enhance sensitivity in gravitational wave detection and accelerate the hunt for enigmatic dark matter.
In this talk, I will delve into various techniques for quantum-enhanced distributed noise sensing, with a focus on their application to dark matter searches. We will explore initial strategies to transcend "Standard Quantum Limits" en route to achieving the ultimate limits of measurement sensitivity set by quantum mechanics. We will also see what important roles that quantum sensor networks and entanglement may have in pushing the boundaries of our sensing capabilities in the future.
Pizza and drinks will be served after the seminar in ATL 2117.
