Researchers have developed a data-driven method to estimate measurement-induced entanglement (MIE) using only measurement records, bypassing the need for extensive post-selection. This approach reframes MIE detection as a learning problem, enabling the use of neural networks for analysis. The method reveals a learnability transition in random circuits: MIE is effectively learnable with polynomial resources below a certain circuit depth, but requires exponential resources above it, coinciding with the breakdown of efficient classical simulation.
