Generation, storage, and validation of metrologically useful many-body entangled states in the analog and digital quantum simulators in the NISQ era

Because of challenges in fault-tolerant quantum computing, the main goal for quantum technologies in the next decade is to generate, characterize, and validate massively correlated quantum states. Non-classical correlations, namely entanglement and Bell correlations, are fundamental properties of the quantum many-body systems and crucial resources for emerging quantum technologies. To fully exploit many-body Bell correlations, we need an experimental protocol to generate such quantum states and a method for classifying the depth of many-body Bell correlations.

This talk will discuss our recently proposed protocols for generating and classifying metrologically useful many-body entangled and many-body Bell correlated states in the quantum simulators based on the ultra-cold quantum gases in the optical lattices. Next, we will discuss perspectives of using hybrid quantum-classical machine learning techniques to generate such many-body Bell correlated states on the parametrized quantum circuits in the Noisy Intermediate-Scale Quantum devices.
