Abstract
Single-photon subtraction (SPS) is useful for engineering optical quantum states and can be accomplished experimentally by heralding on the detection of one photon in the output port of a beamsplitter. Alternatively, conditioning on zero reflected photons modifies states by “zero-photon subtraction” (ZPS). Here we experimentally demonstrate that ZPS reduces the mean photon number of superpositions/mixtures of Fock states. The observed trends in attenuation show a dependence on the Mandel Q parameter for various input states, resulting in complementary behavior between SPS and ZPS. Theoretical results also show higher-order effects on the photon number distribution, beyond reduction in mean photon number.
