A research team from Skoltech and the University of Wuppertal in Germany determined that an all-optical universal logic gate that was previously developed at Skoltech can operate at a speed of 240 GHz at room temperature.

In an article published in the Physical Review B journal, the authors also examined what limits the time between successive polariton condensations by examining the effect of bimolecular quenching—it plays a key role in limiting the speed of transistors.

The Skoltech Laboratory of Hybrid Photonics, headed by Distinguished Professor Pavlos Lagoudakis, Senior Vice President for Fundamental Research at Skoltech and a laureate of the Vyzov Scientific Prize, continues its research project on how to speed up computing and computers with optics.
