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…
Markov chains for tensor network states
S. Iblisdir
Markov chains for probability distributions related to matrix product states and 1D Hamiltonians are introduced. With appropriate 'inverse temperature' schedules, these chains can…
Thermal States of Anyonic Systems
S. Iblisdir, D. Perez-Garcia, M. Aguado +1
A study of the thermal properties of two-dimensional topological lattice models is presented. This work is relevant to assess the usefulness of these systems as a quantum memory. F…
Scaling law for topologically ordered systems at finite temperature
S. Iblisdir, D. Perez-Garcia, M. Aguado +1
Understanding the behaviour of topologically ordered lattice systems at finite temperature is a way of assessing their potential as fault-tolerant quantum memories. We compute the…
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…
