Description
Detecting and manipulating individual atoms with high fidelity is essential for quantum simulation, metrology and, with even more stringent requirements, for quantum computing. I will present our recent results on ultrafast single-atom imaging, based on alternated pulses of highly saturated light addressing the broad 1S0-1P1 transition in ytterbium. With this scheme, we achieve in-trap single-atom detection fidelity and survival probability exceeding 99.8% within just few microseconds.
Beyond single-atom detection, we extend this ultrafast imaging scheme to the detection of multiple atoms in free space with single-particle resolution. By preparing and releasing multiply filled traps, we demonstrate single-atom-resolved detection without parity projection. This capability will enable new explorations of correlations and many-body dynamics in tweezer-trapped atomic ensembles.
Finally, I will also mention the newest tweezer-based quantum platform under construction at the University of Trieste. This system integrates three key components: a quantum computing unit for executing arbitrary operations, a tweezer-cavity interface for cavity quantum electrodynamics and quantum networking experiments, and an atom reservoir to enable fast experimental cycle times and uninterrupted operations. This architecture will serve as a versatile testbed for advancing neutral atom quantum technologies.
