Like snowflakes or fingerprints, no two quantum dots are identical. But a new etching method for shaping and positioning these semiconductor nanocrystals might change that. Tests confirm that etched quantum dots emit single particles of light, boosting prospects for powering new types of devices for quantum communications.
