Generation of Three-Qubit Entangled W-State by Nonlinear Optical State Truncation
arXiv:quant-ph/0607161 · doi:10.1088/0953-4075/39/6/001
Abstract
We propose an alternative scheme to generate W state via optical state truncation using quantum scissors. In particular, these states may be generated through three-mode optical state truncation in a Kerr nonlinear coupler. The more general three-qubit state may be also produced if the system is driven by external classical fields.
