Entangled photon sources are critical to the demonstration and application of many quantum phenomena. Qubitekk’s general-purpose, polarization entangled photon source allows users to spend more time using their entangled photons, and less time constructing and maintaining their source. Qubitekk’s post-selected entanglement source utilizes a bi-photon source connected to an external, removable, non-polarizing beamsplitter to produce post-selected, polarization entangled photons. A useful tool for R&D and product development, Qubitekk’s source is designed to be a rugged, compact, stable, and easy-to-use component for both academic, R&D, and industrial applications.
