A cryogenic neutral atom optical tweezer array

Scalable ultracold Rydberg atom arrays provide an intriguing platform for programmable quantum computation. We present a new system for the control of 2D Rydberg qubit arrays of 87Rb atoms embedded in a cryogenic environment. The setup leverages two main features: a low-vibration cryostat and a high optical access vacuum chamber. Compared to conventional room-temperature setups, cryopumping improves the atom vacuum lifetime to fully leverage the scalability of Rydberg platforms, and a 30 K environment extend the Rydberg lifetime to several times its value at room temperature. The high-optical access vacuum chamber will allow the creation and control of a large array using a 2D optical lattice with the site-resolved addressability and interaction control aided by optical tweezers. We will harness a bi-chromatic magic lattice to provide identical confinement for both ground and Rydberg states. We report our results on trapping atoms within the cryogenic environment, as well as preliminary results on qubit control.
