Scientists at Harvard University have devised a new type of metasurface that can control both the spatiotemporal and quantum properties of transmitted and reflected light.
Rivka Bekenstein, the lead author of the recent paper, said, “Quantum metasurfaces are an entirely new type of materials designed atom by atom, which enable applications such as quantum computation with photons.”
“We combined a state-of-the-art technique for manipulating the state of many atoms by long-range interactions (i.e., Rydberg interactions) with a recent discovery of how a single sheet of atoms can reflect light. We identified an architecture that can be realized in the laboratory, in which a single layer of atoms can act as a switchable quantum mirror.
