2018, Linear Algebra and Its ApplicationsCitation Excerpt :The main effort was to eliminate the error factors created during transmission of quantum information and to describe possible corruption induced in the quantum system. Motivated by a physical problem, Choi et al. in their pioneering articles [7–9], reduced this problem to a purely mathematical introducing the notion of higher rank numerical ranges, and triggering the interest of many authors leading to an extensive literature [1,2,16,17,21]. Due to the unitary invariance property (P2) of the rank-k numerical range, we may assume that A already is in the form (2.1).
