Single photons, individual quanta of the propagating electromagnetic field, serve as excellent quantumness suppliers for quantum communication. Existing single photon sources offer high-quality properties, but they require large working platforms or cryogenic temperatures. As our ability to harness the potential of the quantum realm grows, there is a growing demand for scalable devices. Two-dimensional materials, which are crystals thinned down to a single layer, hold promise in meeting this challenge. Their remarkable flexibility enables us to exploit deformation to tailor their optical and electrical properties. Moreover, they emit single photons if strained, offering a versatile platform for future scalable devices. Thus, what are we waiting for? Gotta stretch 'em all!
