Building a better quantum bit: New qubit breakthrough could transform quantum computing

Phys.org  May 4, 2022
A team of researchers in the US (Argonne National Laboratory, Lawrence Berkeley National Laboratory, research organization, MIT, University of Chicago, National High Magnetic Field Laboratory, Florida State University, Washington University) trapped an electron on an ultrapure solid neon surface in a vacuum. After building their platform, the team performed real-time qubit operations using microwave photons on a trapped electron and characterized its quantum properties. These tests demonstrated that solid neon provided a robust environment for the electron with very low electric noise to disturb it. By using a chip-scale superconducting resonator the team was able to manipulate the trapped electrons, allowing them to read and store information from the qubit, thus making it useful for use in future quantum computers. Most importantly, the qubit attained coherence times in the quantum state competitive with other state-of-the-art qubits. According to the researchers the simplicity of the qubit platform should also lend itself to simple, low-cost manufacturing.
