A promising pairing: Scientists demonstrate new combination of materials for quantum science
Diamond and lithium niobate are often touted as high-performance quantum materials. Now scientists have combined the two materials as a single quantum device. In a study reported in ACS Photonics, researchers sent light from the diamond to the lithium niobate and measured the fraction of light that successfully made it across. The result: An extraordinary 92% of the light made the jump from diamond to lithium niobate. Read More

Helium lifts new quantum computing concept
A team led by Jacob Covey, who is part of Q-NEXT and is an Associate Professor at the University of Chicago, laid out a new concept that could turn helium’s light weight into the next generation of quantum computers. The design relies on helium-3, an isotope with different quantum properties than the helium-4 used to cool MRI machines and fill party balloons. Once built, the computer could use high-powered lasers as “optical tweezers” to capture and control individual atoms of helium. Read More
