Abstract

We describe the quantum transport of electrons by solitary waves and use it as the basis for a scheme for generating a single photon with highly nonclassical nature. A concave soliton acting as an attractive potential can capture an electron in its only eigenstate and the captured electron can be transported by soliton propagation. A single photon is generated by a transition between eigenstates in the interacting soliton potential when a soliton with a captured electron interacts with an empty soliton with a lower eigenstate.
