Unveiling the Secrets of Quantum Physics: The HighEST Project

Highly Entangled States of Matter in Programmable Quantum Devices with Rydberg Atoms: Theory and Experiments – HighEST – is part of the PRIN2022 projects promoted by the MUR.

The HighEST project sets an ambitious goal: to combine an innovative experimental platform with advanced theoretical methods to create new tools capable of characterizing and measuring entanglement in quantum many-body systems. Entanglement is one of the most fascinating challenges of quantum physics and is at the heart of this project.

How Does HighEST Work?

The HighEST team is developing a cutting-edge system that uses focused laser beams to control individual atoms and create complex defect-free quantum systems. This approach will enable the exploration of crucial problems in many-body physics, such as nonequilibrium dynamics in quantum spin models, by leveraging laser excitation to reach Rydberg states. Additionally, protocols will be developed to measure entanglement in systems with around 100 qubits, surpassing the capabilities of current classical hardware.

Why Is It Important?

The experiments conducted by HighEST will serve as a benchmark for parallel theoretical studies on how correlations, fluctuations, topology, and dissipation influence quantum dynamics. These studies are highly relevant not only to statistical physics and condensed matter but also to quantum information.

Project Goals:

• Integrate an innovative experimental platform with advanced theoretical methods.
• Develop new tools to characterize and measure entanglement in quantum many-body systems.
• Explore nonequilibrium dynamics in quantum spin models using defect-free systems.
• Create protocols to measure entanglement in systems with around 100 qubits.
• Provide a benchmark for theoretical explorations on quantum dynamics, with applications in various fields of physics.

Who is Participating?

The project is coordinated by the University of Florence, with the involvement of CNR-INO and the International School for Advanced Studies (SISSA) in Trieste.
