This study presents a method for creating controlled many-body quantum matter using a 51-atom quantum simulator. The system combines deterministically prepared, reconfigurable arrays of individually trapped cold atoms with strong, coherent interactions enabled by excitation to Rydberg states. The researchers realize a programmable Ising-type quantum spin model with tunable interactions and system sizes up to 51 qubits. They observe phase transitions into spatially ordered states that break various discrete symmetries, verify the high-fidelity preparation of these states, and investigate the dynamics across the phase transition in large arrays of atoms. The method enables the exploration of many-body phenomena on a programmable quantum simulator and could lead to new quantum algorithms. The study demonstrates a quantum simulator that can provide unique insights into strongly correlated quantum systems and the role of quantum entanglement. It enables the realization and study of new states of matter, even away from equilibrium, and forms the basis for quantum information processors. The system uses arrays of cold neutral rubidium atoms trapped in optical tweezers, with interactions enabled by Rydberg state excitation. The quantum dynamics are governed by a Hamiltonian that includes terms for coherent coupling, detuning, and interactions between atoms. The researchers observe robust many-body dynamics corresponding to persistent oscillations of the order after a rapid quantum quench. They benchmark the performance of the quantum simulator by comparing the measured build-up of Z2 order with theoretical predictions. The results show excellent agreement with the observed data when finite detection fidelity is accounted for. The study also investigates the quantum dynamics across a phase transition, observing emergent oscillations in many-body dynamics after a sudden quench. These oscillations are robust and persist over several periods with a frequency largely independent of the system size. The study highlights the potential of quantum simulators for exploring many-body phenomena and quantum dynamics in large systems. It demonstrates the feasibility of creating and controlling arrays of hundreds of atoms, and suggests that such systems could be used for quantum optimization algorithms and the study of various quantum phenomena, including quantum critical dynamics, quantum scrambling, and topological states in spin systems. The results challenge conventional theoretical concepts and warrant further studies.This study presents a method for creating controlled many-body quantum matter using a 51-atom quantum simulator.
