Patterned on a microchip and working in ambient conditions, the atoms could lead to rapid advancements in new quantum-based technology. By drilling holes into a thin two-dimensional sheet of hexagonal boron nitride with a gallium-focused ion beam, University of Oregon scientists have created artificial atoms that generate single photons.

The artificial atoms – which work in air and at room temperature – may be a big step in efforts to develop all-optical quantum computing, said UO physicist Benjamín J. Alemán, principal investigator of a study published in the journal Nano Letters.
