  • Noble gas solid-state single electron qubit platform
    Patent number: 12254999
    Abstract: Qubit devices require fast operation, long coherence, and large scalability to be viable for implementation in quantum computing systems. A qubit platform device having long coherence, scalability, and fast operation includes a substrate, or trap region, configured to structurally support solid neon thereon. A trap electrode is configured to provide a trap voltage to the trap region and which creates a confining electrical field to a confining region adjacent to the trap region. The confining region being a region of space to confine an electron therein, confining the electron against the solid neon. First and second sets of guard electrodes are configured to provide variable electric potentials to first and second guard regions to allow for trapping and manipulation of a single electron in the confining region.
