Abstract
We introduce a family of multipartite entanglement
measures called “concentratable entanglements”. These are connected to
previously defined entanglement measures and have an operational
interpretation in terms of probabilistic concentration of entanglement
into Bell pairs. Furthermore, we show that these quantities can be
estimated on a quantum computer by implementing a parallelized SWAP
test, opening a research direction for measuring multipartite
entanglement measures on quantum devices.
