Description
Marcel Krumrein and co-authors published a journal article in 2026 on tiny light guides built into silicon carbide, a hard crystal used in electronics. Inside the crystal sit color centers, flaws that can hold and read out quantum information, meaning data stored in single particles. The team added a mirror to boost the light signal.
Their mirror reflected over 80 percent of light at its peak, across a wide range of colors. At very cold temperatures, the centers gave about 104,000 light counts per second in standard tests. A second checking method raised that to about 125,000 counts. The authors calculate that such rates could allow a correct single reading more than 98 percent of the time.
