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
