Applications of quantum science to computing, cryptography and imaging are on\ntheir way to becoming key next generation technologies. Owing to the high-speed\ntransmission and exceptional noise properties of photons, quantum photonic\narchitectures are likely to play a central role. A long-standing hurdle,\nhowever, has been the realization of robust, device-compatible single photon\nsources that can be activated and controlled on demand. Here we use strain\nengineering to create large arrays of quantum emitters in two-dimensional\nhexagonal boron nitride (hBN). The large energy gap inherent to this Van der\nWaals material stabilizes the emitters at room temperature within nanoscale\nregions defined by substrate-induced deformation of the flake. Combining\nanalytical and numerical modeling we show that emitter activation is likely the\nresult of carrier trapping in deformation potential wells localized near the\npoints where the hBN flake reaches the highest curvature. These findings,\ntherefore, hint at novel opportunities for the manipulation of single photon\nsources through the combined control of strain and external electrostatic\npotentials under ambient conditions.\n
