Title: Remotely projecting states of photonic temporal modes
Authors: Vahid Ansari, John M. Donohue, Benjamin Brecht, and Christine Silberhorn
Abstract summary: We show remote spectral shaping of single photon states and probe the coherence properties of two-photon quantum correlations in the time-frequency domain. We control the temporal mode structure between the generated photon pairs and show remote state-projections over a range of time-frequency mode superpositions.

Abstract: Two-photon time-frequency entanglement is a valuable resource in quantum information. Resolving the wavepacket of ultrashort pulsed single-photons, however, is a challenge. Here, we demonstrate remote spectral shaping of single photon states and probe the coherence properties of two-photon quantum correlations in the time-frequency domain, using engineered parametric down-conversion (PDC) and a quantum pulse gate (QPG) in nonlinear waveguides. Through tailoring the joint spectral amplitude function of our PDC source we control the temporal mode structure between the generated photon pairs and show remote state-projections over a range of time-frequency mode superpositions.
