A Measure of Stregth of an Unextendible Product Basis
arXiv:quant-ph/0105125 · doi:10.1103/PhysRevA.65.042322
Abstract
A notion of strength of an unextendible product basis is introduced and a quantitative measure for it is suggested with a view to providing an indirect measure for the bound entanglement of formation of the bound entangled mixed state associated with an unextendible product basis.
