Description
Many-spin entanglement is investigated in a gas of spin-carrying molecules (atoms) in a nanopore under NMR conditions with a dipolar ordered initial state. To estimate the number of entangled spins, the second moment of the distribution of the intensities of multiple quantum (MQ) NMR coherences is used, which provides a lower bound for the quantum Fisher information. Many-spin entanglement is investigated at different temperatures and different numbers of spins.
