Solid-state based quantum emitter arrays as quantum metasurfaces 

In 2020 we suggested quantum metasurfaces as a new platform for quantum optics [1]. Quantum metasurfaces are subwavelength atomic arrays that quantum control the response to light by employing the enhanced collective response of subwavelength arrays along with Rydberg long-range interactions. Our original proposal was soon experimentally realized with ultra-cold atomic arrays and followed by many theoretical proposals, employing quantum metasurfaces to entanglement generation protocols and computing.

The seminar will describe our work of subwavelength silicon-vacancy center arrays as a realization of quantum metasurfaces [1]. I will present demonstrations of coherent optical response of these quantum emitters arrays to light, and our planned path toward scalable quantum information. I will describe our developed theoretical protocols for quantum control by employing lattices’ symmetry breaking, extending our theory in [2] to other geometries and experimental scenarios. I will then discuss how integration of the SiV arrays with nanophotonics elements affects the response to light, enabling exploration of both fundamental phenomena [3] and improved fidelities. Finally, I will briefly review our work of simulating Post-Newtonian gravity with long-ranged nonlinear optics [4].
