Loschmidt cooling by time reversal of atomic matter waves
J. Martin, B. Georgeot, D. L. Shepelyansky
We propose an experimental scheme which allows to realize approximate time reversal of matter waves for ultracold atoms in the regime of quantum chaos. We show that a significant f…
How many CNOT gates does it take to generate a three-qubit state ?
Marko Znidaric, Olivier Giraud, Bertrand Georgeot
The number of two-qubit gates required to transform deterministically a three-qubit pure quantum state into another is discussed. We show that any state can be prepared from a prod…
Multifractality and intermediate statistics in quantum maps
J. Martin, O. Giraud, B. Georgeot
We study multifractal properties of wave functions for a one-parameter family of quantum maps displaying the whole range of spectral statistics intermediate between integrable and…
Interference versus success probability in quantum algorithms with imperfections
Daniel Braun, Bertrand Georgeot
We study the influence of errors and decoherence on both the performance of Shor's factoring algorithm and Grover's search algorithm, and on the amount of interference in these alg…
