Demonstrating highly symmetric single-mode, single-photon heralding efficiency in spontaneous parametric downconversion.
We demonstrate a symmetric, single-spatial-mode, single-photon heralding efficiency of 84% for a type-II spontaneous parametric downconversion process. High-efficiency, single-spatial mode collection is key to enabling many quantum information processing and quantum metrology applications.
