Title: Generation of optical coherent-state superpositions by number-resolved photon subtraction from the squeezed vacuum
Published: September 09, 2010
Abstract: We have created heralded coherent-state superpositions (CSSs) by subtracting up to three photons from a pulse of squeezed vacuum light. To produce such CSSs at a sufficient rate, we used our high-efficiency photon-number-resolving transition edge sensor to detect the subtracted photons. This experiment is enabled by and utilizes the full photon-number-resolving capabilities of this detector. The CSS produced by three-photon subtraction had a mean-photon number of 2.75+0.06 −0.24 and a fidelity of 0.59+0.04 −0.14 with an ideal CSS. This confirms that subtracting more photons results in higher-amplitude CSSs.
