Analysis

This paper challenges the conventional understanding of quantum entanglement by demonstrating its persistence in collective quantum modes at room temperature and over macroscopic distances. It provides a framework for understanding and certifying entanglement based on measurable parameters, which is significant for advancing quantum technologies.

Reference

The paper derives an exact entanglement boundary based on the positivity of the partial transpose, valid in the symmetric resonant limit, and provides an explicit minimum collective fluctuation amplitude required to sustain steady-state entanglement.
