Time evolution of negative binomial optical field in a diffusion channel

Tang-Kun Liu, Pan-Pan Wu, Chuan-Jia Shan +2 more

We find the time evolution law of a negative binomial optical field in a diffusion channel. We reveal that by adjusting the diffusion parameter, the photon number can be controlled. Therefore, the diffusion process can be considered a quantum controlling scheme through photon addition.

Statistical properties of binomial and negative-binomial combinational optical field state and its generation in quantum diffusion channel

Fan Hong‐Yi, Ze Wu

According to the combinational binomial-negative-binomial distribution, we propose a binomial-negative-binomial combinational optical field state, which can be generated in the process of a Fock state |m>m| passing through a quantum-mechanical diffusion channel. We derive the second-order coherence degree formula, g(2)(t) =2-((m2+m)/(m+κt2)), which is the diffusion constant. We find that in the process of the Fock state undergoing quantum diffusion and becoming classical, the corresponding photon statistics evolves from sub-Poissonian distribution to Poisson distribution and finally goes to a chaotic state. We also find that the more photons in the initial Fock state, the longer time is needed for quantum decoherence.According to the combinational binomial-negative-binomial distribution, we propose a binomial-negative-binomial combinational optical field state, which can be generated in the process of a Fock state |m>m| passing through a quantum-mechanical diffusion channel.

Evolution law of a negative binomial state in an amplitude dissipative channel

Feng Chen, Hong-Yi Fan

For the first time we derive the evolution law of the negative binomial state in an amplitude dissipative channel with a damping constant κ. We find that after passing through the channel, the final state is still a negative binomial state, however the parameter γ evolves into γ', where γ = γ/(e−2κt (1 − γ) + γ). The decay law of the average photon number is also obtained.
