Título: | Efficient generation of random multipartite entangled states using time-optimal unitary operations |
Autor: | Borras, A.; Majtey, A. P.; Casas, Montserrat CSIC | Fecha de publicación: | 19-ago-2008 | Editor: | American Physical Society | Citación: | Physical Review A 77: 05311 (2008) | Resumen: | We review the generation of random pure states using a protocol of repeated two-qubit gates. We study the dependence of the convergence to states with Haar multipartite entanglement distribution. We investigate the optimal generation of such states in terms of the physical (real) time needed to apply the protocol, instead of the gate complexity point of view used in other works. This physical time can be obtained, for a given Hamiltonian, within the theoretical framework offered by the quantum brachistochrone formalism, the quantum analogue to the brachistochrone problem in classical mechanics [ Carlini et al. Phys. Rev. Lett. 96 060503 (2006). Using an anisotropic Heisenberg Hamiltonian as an example, we find that different optimal quantum gates arise according to the optimality point of view used in each case. We also study how the convergence to random entangled states depends on different entanglement measures. | Descripción: | PACS number s : 03.67.Bg, 03.67.A | Versión del editor: | http://dx.doi.org/10.1103/PhysRevA.78.022328 | URI: | http://hdl.handle.net/10261/47128 | DOI: | 10.1103/PhysRevA.78.022328 | ISSN: | 1050-2947 | E-ISSN: | 1094-1622 |
