    "abstract": "The Groverian entanglement measure, G(psi), is applied to characterize a\nvariety of pure quantum states |psi\u003e of multiple qubits. The Groverian measure\nis calculated analytically for certain states of high symmetry, while for\narbitrary states it is evaluated using a numerical procedure. In particular, it\nis calculated for the class of Greenberger-Horne-Zeilinger states, the W states\nas well as for random pure states of n qubits. The entanglement generated by\nGrover\u0027s algorithm is evaluated by calculating G(psi) for the intermediate\nstates that are obtained after t Grover iterations, for various initial states\nand for different sets of the marked states.",
