What to know about 'Atom Camera' maps laser light at nanoscale using a single ultracold atom

Researchers at the Institute for Molecular Science have developed the 'Atom Camera,' a microscopy technique using a single ultracold rubidium atom to visualize light intensity and polarization at the nanoscale. This method surpasses the diffraction limit of conventional microscopes and is intended to aid in the development of neutral-atom quantum computers.
