Scientists from Katsaros group at IST Austria found a new and promising qubit in Ge quantum wells and published their exceptional results in the prestigious journal Nature Materials. Such Ge quantum wells are investigated at IST because of their potential as a platform for fully electrically tunable spin-orbit qubits and are particularly attractive in terms of scalability. The authors findings emphasize the potential of this material for on-chip integration with superconducting technologies. The large out of plane g-factors and the spin-orbit energy similar to what has been reported for III-V materials makes these Ge hole gases not only a suitable platform for spin qubits but also for investigating topological superconductivity.
