No-go theorem for entanglement distillation using catalysis
Ludovico Lami, Bartosz Regula, Alexander Streltsov
Abstract
Not all entanglement is distillable, i.e., extractable in pure form. In this work, the authors show that being assisted by catalysts, which generally can help transform quantum states, is not enough to change this; certain entangled states will stay ``bound entangled'' even when catalysts are allowed.
