In the final part of this series, we zero in on three photonics technologies expected to be essential for demanding computing and communication systems of the future.
Tucked inside one of Nvidia’s sprawling research campuses, engineers in a climate-controlled cleanroom are wrestling with a problem that could define the next era of computing: how to move light, not electrons, across chips to eliminate the growing bottleneck of data transfer in AI supercomputers.
A few hundred miles away, in a lab at the University of Virginia, physicists are preparing squeezed-light states to push past quantum limits of detection. Across the Atlantic, researchers in Europe are delicately integrating quantum dots and nanodiamonds into microscopic circuits to send single photons down optical fibers—one by one, with perfect precision.
