Abstract: Optical nanoantenna field enhancement is hampered by material- and size-dependent losses. Researchers have now made an atomic antenna using the controlled formation of an isolated germanium vacancy colour centre in diamond, which enables giant near-field optical enhancement and which can detect and control nearby charges and induce energy transfer.
