Preparation of Knill-Laflamme-Milburn states using a tunable controlled phase gate
Original language description
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 (Knill et al 2001 Nature 409 46). Although the usage of such states is widelyinvestigated, considerably less effort has been invested into experimentally accessible preparation schemes. This paper discusses the possibility of employing a tunable controlled phase gate to generate an arbitrary KLM state. In the first part, the idea of using the controlled phase gate is explained on the case of two-qubit KLM states. Optimization of the proposed scheme is then discussed for the framework of linear optics. Subsequent generalization of the scheme to the arbitrary n-qubit KLM state isderived in the second part of this paper.
