The diffraction limit prevents a conventional optical microscope from imaging at the nanoscale. However, nanoscale imaging of molecules is possible by exploiting an intensity-dependent molecular switch1–3. This switch is translated into a microscopy scheme, stimulated emission depletion microscopy4–7. Variants on this scheme exist3,8–13, yet all exploit an incoherent response to the lasers. We present a scheme that relies on a coherent response to a laser. Quantum control of a two-level system… CONTINUE READING
