Ground state entanglement in quantum spin chains
J. I. Latorre, E. Rico, G. Vidal
A microscopic calculation of ground state entanglement for the XY and Heisenberg models shows the emergence of universal scaling behavior at quantum phase transitions. Entanglement…
Natural majorization of the Quantum Fourier Transformation in phase-estimation algorithms
Roman Orus, Jose I. Latorre, Miguel A. Martin-Delgado
We prove that majorization relations hold step by step in the Quantum Fourier Transformation (QFT) for phase-estimation algorithms considered in the canonical decomposition. Our re…
Time-optimal Hamiltonian simulation and gate synthesis using homogeneous local unitaries
Ll. Masanes, G. Vidal, J. I. Latorre
Motivated by experimental limitations commonly met in the design of solid state quantum computers, we study the problems of non-local Hamiltonian simulation and non-local gate synt…
Realization of symmetries and the c-theorem
S. Forte, J. I. Latorre
We discuss the relation between the --theorem and the the way various symmetries are realized in quantum field theory. We review our recent proof of the --theorem in four dim…
