    "abstract": "We consider pure quantum states of N qubits and study the genuine N-qubit\nentanglement that is shared among all the N qubits. We introduce an\ninformation-theoretic measure of genuine N-qubit entanglement based on\nbipartite partitions. When N is an even number, this measure is presented in a\nsimple formula, which depends only on the purities of the partially reduced\ndensity matrices. It can be easily computed theoretically and measured\nexperimentally. When N is an odd number, the measure can also be obtained in\nprinciple.",
