Entangled photon-pair sources are at the core of quantum applications like quantum key distribution, sensing, and imaging. Operation in space-limited and adverse environments such as in satellite-based and mobile communication requires robust entanglement sources with minimal size and weight requirements. Here, we meet this challenge by realizing a cubic micrometer scale entangled photon-pair source in a 3R-stacked transition metal dichalcogenide crystal.

CS has high nonlinearity, narrow Raman lines, a broad transmission spectrum, and also has a large index contrast with the microstructured silica fiber. We can achieve phase matching over a large spectral range by tuning the pump wavelength, allowing the generation of idler photons in the infrared region, which is suitable for applications in quantum spectroscopy.

- The study explores how photon pairs are generated through a process called spontaneous four-wave mixing in a specific type of optical fiber that is liquid-filled and microstructured.
- It demonstrates the capability to control important properties like wavelength, group velocity, and bandwidth of the produced two-photon states.
- The focus is on generating a factorable state, which maintains no correlation between the two photons and enables the creation of a single-photon state without needing complex filtering techniques.
