Recently, Rydberg atoms trapped in optical tweezer has been a central topic of intense research interest with application ranging from quantum metrology, quantum simulation and quantum computation. Based on the technique of adiabatic preparation of the manybody ground state with the reconfigurable Rydberg array, we could probe the critical physics predicted by conformal field theory. In this talk, I will describe how we build up the system and adiabatically prepare the ground state. With the existence of various practical imperfections, we performed numerical and experimental investigation of possible error sources and achieved quantitative agreements with the CFT results of the scaling components. With some technical upgrade, it could provide predictions in higher dimensions. This platform also paves the way for a dual-species Rydberg platform with the possible application of measurement assisted long-range entanglement and scalable quantum error correction.
