Abstract
Single atom imaging requires discrimination of weak photon count events above the background and has typically been performed using electron-multiplying charge-coupled device cameras, photomultiplier tubes, or single photon counting modules. A scientific complementary metal-oxide semiconductor (sCMOS) provides a cost effective and highly scalable alternative to other single atom imaging technologies, offering fast readout and larger sensor dimensions. We demonstrate single atom resolved imaging of two site-addressable optical traps separated by 10 μm using an sCMOS camera, offering a competitive signal-to-noise ratio at intermediate count rates to allow high fidelity readout discrimination (error <10−6) and sub-μm spatial resolution for applications in quantum technologies.

Recent developments in quantum information processing (QIP) have led to a requirement for resolved single atom imaging of isolated atomic qubits in microscopic optical traps,1,2 ion traps,3 or optical lattices where quantum gas microscopes offer a route to quantum simulation
