Macroscopic quantum superpositions by means of single-atom dispersion
Craig M. Savage, Samuel L. Braunstein, Daniel F. Walls · Optics Letters · 1990
We show that macroscopic quantum superpositions of the electromagnetic field can be generated through amplification of microscopic quantum superpositions prepared in a single atom. Our scheme has the advantage that dissipation is negligible, and hence the superpositions are not rapidly destroyed.
