Summary

Story summary

Researchers created a measurement-only dynamics framework that generates strong entanglement through repeated local measurements without intrinsic unitary dynamics.
They used a one-dimensional model with a fermionic chain and an auxiliary chain, achieving volume-law entangled states via one-body operator measurements.
Control over entanglement was shown by applying kinetic constraints with higher-body operator measurements.
Findings indicate that entanglement entropy grows with the system's volume, enhancing understanding of non-unitary many-body dynamics.
The research suggests potential applications for measurement-induced phase transitions in future quantum technologies.
