摘要: 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 sufficient rate, we used our high-efficiency photon-number-resolving transition edge sensor detect the subtracted photons. This experiment is enabled and utilizes full capabilities this detector. The CSS produced three-photon subtraction had mean-photon number $2.{75}_{\ensuremath{-}0.24}^{+0.06}$ fidelity $0.{59}_{\ensuremath{-}0.14}^{+0.04}$ with an ideal CSS. confirms that more results in higher-amplitude CSSs.
