Quantum dynamics of three-dimensional Rydberg-atom systems

There is a great interest for Rydberg-atom programmable quantum simulators because of their advantages in scalability and arbitrary control of individual interactions via Rydberg states [1]. Here we report, three-dimensional quantum systems are constucted with rubidium single atoms arranged by 250 holographic optical tweezers and entangled through Rydberg-state excitation. Their quantum dynamics are successfully observed for various symmetric structures and analyzed with Lindblad master equations for coherent and dissipative many-body system behaviors [2]. Their scaling behavior in the intermediate-scale quantum simulation regime of N$=$50-100 are to be presented. [1] A. Browaeys and T.
