Obtaining a single-photon weak value from experiments using a strong (many-photon) coherent state
A common type of weak-value experiment prepares a single particle in one state, weakly measures the occupation number of another state, and post-selects on finding the particle in a third state (a 'click'). Most weak-value experiments have been done with photons, but the heralded preparation of a single photon is …
