Generation of three-qubit entangled W state by nonlinear optical state truncation

We propose an alternative scheme to generate the 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 also be produced if the system is...

Zusammenfassung:	We propose an alternative scheme to generate the 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 also be produced if the system is driven by external classical fields.
