New trapped-atom qubit technology translates to industry-ready quantum computing product
A team of engineers and physicists at the University of Wisconsin-Madison led by Mikhail Kats and Mark Saffman have developed an ingenious method for trapping atoms of different species to make qubits. Capturing two types of neutral atoms next to each other, the method creates interleaved grids of cesium and rubidium atoms that can be used as qubits in quantum computing and quantum sensing. The setup is much simpler and more cost-effective than previous efforts to isolate and form interleaved grids of atoms and is already being used in early-stage quantum devices. Read More
