Quantum thermalization achieves optimal approximate quantum error correction
A new preprint on arXiv examines the relationship between quantum thermalization and quantum error correction, noting that both processes hide information from local measurements. The work reports that the dynamics of thermalizing many-body systems can be used to achieve optimal approximate quantum error correction.

Experimental quantum simulators could begin benchmarking approximate QEC protocols based on thermalization, turning natural many-body dynamics into a resource rather than a noise source.
Platforms such as neutral-atom and trapped-ion systems already exhibit controllable many-body thermalization and allow local measurements. If the optimality result holds, these existing setups could implement the proposed approximate codes and compare their performance against small exact codes within the next two years.
