摘要：

We have created heralded coherent-state superpositions (CSSs) by subtracting up to three photons frompulse 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(-0.24)(+0.06) and a fidelity of 0.59(-0.14)(+0.04) with an ideal CSS. This confirms that subtracting more photons results in higher- amplitude CSSs.
