"enables operating tens of millions quantum computing units inside few mm2-sized silicon chip... using 16 quantum state antimony atom (nucleus having 8 distinct quantum states, plus an electron with 2 quantum states) encoding quantum information 4 ways: magnetic field controls electron, nucleus, electric field control nucleus or flip-flop qubit nucleus and electron in opposition to each other... encode logical qubit within atom built upon >2 quantum levels, getting enough redundancy to detect and correct errors as they occur."
