Preparation of Knill–Laflamme–Milburn states using a tunable controlled phase gate
A specific class of partially entangled states known as Knill-Laflamme-Milburn states (or KLM states) has been proved to be useful in relation to quantum information processing [1].Although the usage of such states is widely investigated, considerably less effort has been invested into experimentally accessible preparation schemes.This paper discusses the possibility …
