Abstract
AbstractHigher‐order nonclassical properties of r photon added and t photon subtracted qudit states (referred to as rPAQS and tPSQS, respectively) are investigated here to answer: How addition and subtraction of photon can be used to engineer higher‐order nonclassical properties of qudit states? To obtain the answer, higher‐order moment of relevant bosonic field operators is first obtained and subsequently used to study the higher‐order nonclassical properties (e.g., higher‐order antibunching, higher‐order squeezing, and higher‐order sub‐Poissonian photon statistics) of the corresponding states. These witnesses establish that rPAQS and tPSQS are highly nonclassical. To quantitatively establish this observation and to make a comparison between rPAQS and tPSQS, volumes of the negative part of Wigner function are computed. Finally, for the sake of verifiability of the obtained results, optical tomograms are also reported. Throughout the study, a particular type of qudit state named as a new generalized binomial state is used as an example.
