Combining trapped atoms and photonics for new quantum devices
From the University of Chicago: Researchers have discovered how to combine two powerful technologies — trapped atom arrays and photonic devices — to yield advanced systems for quantum computing, simulation and networking. The new combination will allow the construction of large quantum systems which can be easily scaled up, by leveraging photonics to interconnect individual atom arrays. Read More

New method could yield fast, cross-country quantum network
Scientists have struggled to come up with practical methods of building networks that can connect quantum computers. Now, researchers at the University of Chicago have proposed a new approach — building long quantum channels using vacuum sealed tubes with an array of spaced-out lenses. These vacuum beam guides would have ranges of thousands of kilometers and capacities of 10 trillion qubits per second, better than any existing quantum communication approach. 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
