摘要

众所周知，光子与自由电子的相互作用导致了它们的量子纠缠和新的统计。通常，研究光子与物质相互作用时的统计性质是考虑单色光子的。在现实中，没有完全单色的光子，这一点必须加以考虑。本文证明了非单色光子的统计性质及其量子纠缠与单色光子的统计性质有很大的不同。结果表明，改变光子谱线宽度的参数可以很容易地改变光子统计量。所得结果可用于需要光子态的量子技术，而其他方法无法实现光子态。

Statistics of non-monochromatic photons interacting with free electrons

It is well known that the interaction of photons with free electrons leads to their quantum entanglement and new statistics. Often, the study of the statistical properties of photons during their interaction with matter is considered for monochromatic photons. In reality, there are no completely monochromatic photons, and this must be taken into account. In this paper, it is shown that the statistical properties of non-monochromatic photons and their quantum entanglement can differ significantly from the case of monochromatic photons. It is shown that the photon statistics can be changed quite easily by varying the parameter responsible for the width of the spectral line of photons. The results obtained can be used in quantum technologies where photon states are needed that are not realized by other methods.
