Embezzlement of entanglement is an exotic phenomenon in quantum
information science, describing the possibility of extracting
entanglement from a resource system without changing its quantum state
In this context, the resource systems play the role of a catalyst,
enabling a state transition that would otherwise be impossible, without
being consumed in the process.
...So far, it seemed highly questionable that physical systems
exhibiting such strong entanglement properties could exist in the first
place.
"Thus, we became curious whether universal embezzlement is in fact abundant and, for example, also materializes in the simpler setting of spin chains in many-body physics
Notably, the researchers showed that embezzlement could also survive in an approximate form in finite systems, thus it is not a theoretical construct that only shows up in ideal infinite models, but instead could also emerge in real and finite quantum systems. In their next studies, they hope to further assess the validity of their theory.
