This study investigates the effect of coherent state superposition on quantum scissors. The scissor is subjected to ideal single-photon, vacuum state, and superpositions of coherent states as incident fields. Detectors are employed to measure single photons and zero photons, resulting in a superposition state of single-photon and vacuum states at the output. The study calculates the scissor's probability of success, amplification factor, fidelity, and efficiency factor. The probability of success depends on the coherent field's amplitude, incident field phase, and transmission coefficients of the beam splitters. The maximum probability of success reaches 25%, attributed to even coherent state superpositions. Quantum scissors demonstrate the capability to amplify states under specific conditions. Results indicate maximum amplification when the incident field phase approximates π. Besides amplification, this phase significantly influences the distribution of zero and single-photon states in the superposition output. Thus, altering the incident field phase or beam splitter transmission can modify this distribution. For a fixed incident field intensity, closer proximity of the incident phase to π correlates with reduced scissor efficiency. These findings underscore how quantum scissors can characterize coherent state superpositions due to their sensitivity to incident state characteristics.
