"quantum behavior in larger molecular structures difficult to work with as thermal noise/ interaction with supporting substrates destroys coherence... overcome utilizing scanning tunneling microscope/ sub-Kelvin cooling isolating individual phthalocyanine molecules on pristine silver surface... residual rotational/ vibrational energy stripped away by tuning localized electronic pulses, freezing molecules into single, unperturbed quantum ground state... stable molecular qubits, nanoscale chemical reaction control"
