Query: Spectral and Temporal Measurement of Entangled Photon Interaction with a
  Virtual State Mediated Two-Photon Transition   Entangled photon pairs are predicted to linearize and increase the efficiency
of two-photon absorption, allowing continuous wave laser diodes to drive
ultrafast time-resolved spectroscopy and nonlinear processes. Despite a range
of theoretical studies and experimental measurements, inconsistencies persist
about the value of the entanglement enhanced interaction cross section. A
spectrometer is constructed that can temporally and spectrally characterize the
entangled photon state before, during, and after any potential two-photon
excitation event. For the molecule Rhodamine 6G, which has a virtual state
pathway, any entangled two-photon interaction is found to be equal to or lower
than classical, single photon scattering events.
