Vectorial field reconstruction without detecting the field

Jonas Vasikonis, Jorge Fuenzalida, Markus Gr\"afe, Satyajeet Patil, Sebastian T\"opfer

The full vectorial structure of an undetected beam can be recovered by measuring interference in its detected partner photon field.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Using phase-shifting and off-axis quantum holography with two polarization projections, we reconstruct the horizontal and vertical amplitudes and their relative phase across the beam profile, thereby recovering the full vectorial structure of the undetected field.

C2weakest assumption

The assumption that momentum correlations and pathway indistinguishability transfer the undetected idler's local polarization information to the detected signal without significant loss, distortion, or cross-talk from experimental imperfections or imperfect phase matching.

C3one line summary

The full vectorial structure of an undetected telecom-wavelength vector beam is reconstructed from interference in its detected visible signal partner using induced coherence and quantum holography.
