Forming and sensing optical emitters in real time

Seeking new techniques to enable quantum networking, Harvard University researchers have developed a novel laser-based strategy for creating single-atom, near-surface material defects, which can be used to form qubits, the ...

How one photon becomes four charge carriers

Photovoltaics, the conversion of light to electricity, is a key technology for sustainable energy. Since the days of Max Planck and Albert Einstein, we know that light as well as electricity come in tiny, quantized packets ...
