英文摘要 | Given a starting quantum state and a target quantum state, and a driving Hamiltonian, how fast can the starting state evolve into the target state according to the Schrodinger dynamics? This problem arises in a variety of contexts such as quantum computation, quantum control, and in particular, the problems of maximum information processing rate of quantum systems. We will establish a new time-energy uncertainty relation, which provides a general upper bound estimation of the evolution speed. A naive yet fundamental example which has interesting implications for quantum search is worked out explicitly.: (C) 2003 Elsevier B.V. All rights reserved. |
