As AEM said, the brazilian group of quantum optics at UFRJ has worked on this subject a lot.

When does entanglement actually end?

Entanglement appears to persist until an irreversible measurement is made, which collapses the wave function and ends observable entanglement. The discussion highlights that passing through a polarizing beam splitter does not necessarily end entanglement if the paths can be recombined, suggesting that entanglement is contingent on what can be known about the particles. Measurement, whether active or passive, plays a crucial role in determining the state of entangled particles, and this process can lead to further entanglement between the observer and the system. The conversation also touches on the complexities of quantum mechanics interpretations, such as the many-worlds interpretation and the implications of wave function collapse. Ultimately, the nature of entanglement and measurement remains a nuanced topic in quantum physics.
