Phase tomography of spontaneously emitted photon-pairs

We have directly measured the joint spectral phase of spontaneously emitted photon-pairs for the first time. We have devised a novel tomographic method using quantum interference of bi-photon functions. This method can potentially be used for quantum sensing. (c) 2021 The Author(s)

Automated summary

The study directly measured the joint spectral phase of spontaneously emitted photon-pairs, and introduced a novel tomographic method using quantum interference of bi-photon functions, which could potentially be applied in quantum sensing.
