Dicke states是什么
WebMost Dicke states produced so far are limited to pseudospin-1/2 (two-level) particles. In this work, we deterministically generate balanced spin-1 Dicke states in the close vicinity of l=N,m=0〉 with N~11700, by driving a spin-1 condensate through a quantum phase transition. The prepared states are characterized to exhibit a collective spin ... WebFeb 22, 2016 · The antisymmetric, or “dark,” states that form in subradiant systems can store photons—and the information encrypted onto them—for a long time. These states can therefore be the backbone for new types of quantum memories [ 8 ]. For example, a recent proposal [ 9] outlines a protocol for switching between subradiant and superradiant ...
