    • Eq. 1 is a representation of the transition from initial to final states of the particles as a result of the entanglement with and subsequent detection of the photon. A more rigorous treatment is presented later in the paper.

    • note
    • Introducing a lens requires a sum over all paths from particle to detector through the non-zero aperture of the lens, which gives a superposition of many momentum kicks to the particle [hence the integral in Eq. 4 of (9)], thus reducing its position uncertainty.

    • note
    • The nonscattering term depends on the total scattering rate over all angles (a function of r) and can be derived from the optical theorem (19). Additional considerations of scattering efficiency are straightforward and only affect the rate of localization.
