European, Russian Physicists Push Step Closer to Semiconductor Use for Quantum Computing
Scientists send light through 2D crystal layer in quantum computing leap
Excerpts and salient points ~
+ One of the problems is that researchers haven’t been able to develop a practical and effective platform for moving photons around. Scientists have previously tested a variety of solutions with middling results: superconducting circuits, cold atoms, ions, defects in diamonds.
“I foresee that in the near future, two-dimensional monoatomic crystals will be used to transfer information in quantum devices,” Alexey Kavokin, professor at St. Petersburg University in Russia.
+ Now, scientists have new a platform. In a series of lab tests, researchers in Germany, Russia and France successfully propagated light through two-dimensional crystals. For the tests, researchers used a one-atom-thick layer of molybdenum diselenide, MoSe2 — the world’s thinnest crystal semiconductor.
+ The results — detailed this week in the journal Nature Nanotechnology — showed the polarization, or spin direction of the beam of photons, depended on the direction the light traveling through the crystal layer.
