论文摘要
我们构建了一类哈密顿人，它们从头到尾都描述了光电检测过程。我们的哈密顿人描述了光子的创建，光子如何传播到吸收者（例如分子），分子如何吸收光子以及在不可逆地更改其构型后的分子如何触发扩增过程 - 在波长下可能与光子波长的波长有很大不同，从而与光子的波长产生了很大不同。我们使用简单的原型哈密顿量来分析中的单光子检测过程，在海森伯格图片中，该过程整齐地与不良效果分开了可取的效果。指出了对更复杂的哈密顿人的扩展。
We construct a class of Hamiltonians that describe the photodetection process from beginning to end. Our Hamiltonians describe the creation of a photon, how the photon travels to an absorber (such as a molecule), how the molecule absorbs the photon, and how the molecule after irreversibly changing its configuration triggers an amplification process---at a wavelength that may be very different from the photon's wavelength---thus producing a macroscopic signal. We use a simple prototype Hamiltonian to describe the single-photon detection process analytically in the Heisenberg picture, which neatly separates desirable from undesirable effects. Extensions to more complicated Hamiltonians are pointed out.
