Conditional generation scheme for high-fidelity Yurke-Stoler states by mixing two coherent beams with a squeezed vacuum state
Sun-Hyun Youn · Journal of the Korean Physical Society · 2015
The numerical conditions to generate high-fidelity Yurke-Stoler states (|α > +e iψ | − α >)were found for two cascade-placed beam splitters with one squeezed state input and two coherent state inputs. Controlling the amplitudes and the phases of beams allows for various Yurke-Stoler states to be manipulated with ultra-high fidelity, and the expected theoretical fidelity is more than 0.9999.
