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.
