Generating new nonclassical state by repeatedly operating number operator on coherent state
Gang Ren, Jian-ming Du, Wen‐Hai Zhang · Modern Physics Letters B · 2021
In this paper, using the principle of quantum state superposition, we report a nonclassical quantum state which is constructed by repeatedly operating the number operator on the coherent state. Nonclassical effects of this state are discussed by photon-number distribution, sub-Poissonian statistics, anti-bunching and negativity of Wigner function and squeezing effect. Our work provides an important nonclassical resource, which may be used in quantum communication and quantum optics.
