Probing thermalization through spectral analysis with matrix product operators
Yilun Yang, Sofyan Iblisdir, J. Ignacio Cirac +1
We combine matrix product operator techniques with Chebyshev polynomial expansions and present a method that is able to explore spectral properties of quantum many-body Hamiltonian…
Generalised Asymmetric Quantum Cloning
S. Iblisdir, A. Acin, N. Gisin
We study machines that take N identical replicas of a pure qudit state as input and output a set of M_A clones of a given fidelity and another set of clones of another fideli…
Quantum cloning of orthogonal qubits
J. Fiurasek, S. Iblisdir, S. Massar +1
An optimal universal cloning transformation is derived that produces M copies of an unknown qubit from a pair of orthogonal qubits. For M>6, the corresponding cloning fidelity is h…
Optimal cloning of coherent states with a linear amplifier and beam splitters
Samuel L. Braunstein, Nicolas J. Cerf, Sofyan Iblisdir +2
A transformation achieving the optimal symmetric N-to-M cloning of coherent states is presented. Its implementation only requires a phase-insensitive linear amplifier and a network…
