The paper reports the first realization of alkaline-earth circular Rydberg atoms trapped in optical tweezers, demonstrating the creation of very high-$n$ ($n = 79$) circular states of ${}^{88}$Sr. The atoms are trapped using the optically active Sr$^+$ core, which allows for conservative trapping in standard Gaussian beam tweezers. The authors achieve lifetimes of 2.55 ms at room temperature by cavity-assisted suppression of black-body radiation. They also demonstrate coherent control of a microwave qubit encoded in circular states separated by two principal quantum numbers and characterize the qubit coherence time via Ramsey and spin-echo spectroscopy. The trapping potential is quantified, showing that the Sr$^+$ core polarizability enables trapping in a standard Gaussian beam tweezer. The results open new avenues for quantum simulations with circular Rydberg states of divalent atoms, leveraging the unique properties of the optically active core ion.The paper reports the first realization of alkaline-earth circular Rydberg atoms trapped in optical tweezers, demonstrating the creation of very high-$n$ ($n = 79$) circular states of ${}^{88}$Sr. The atoms are trapped using the optically active Sr$^+$ core, which allows for conservative trapping in standard Gaussian beam tweezers.
