Quantum entanglement can multiply a network's capacity 88-fold?

Previous results suggested quantum entanglement only nudges classical communication capacity up by a few percent. This work shows that when senders know the channel state in real time, entanglement shared among transmitters can multiply total capacity by factors exceeding 88× (with just 7 users and binary signals), with gains that grow exponentially as more users are added. The advantage survives substantial noise — even if 30% of the entangled qubits are completely scrambled.
