Abstract
The numerical conditions to generate a high-fidelity Yurke-Stoler states $|α>+ ei ψ |-α>$were found for two cascade-placed beam splitters with one squeezed state input and two coherent state inputs. Controlling the amplitude and the phases of beams, allows for various Yurke-Stoler states to be manipulated with ultra high-fidelity, and the expected theoretical fidelity is of more than 0.9999.
