  • High-voltage glitch-suppressed semiconductor switch for quantum object confinement apparatus
    Patent number: 12689365
    Abstract: A quantum object confinement apparatus comprising one or more high-voltage semiconductor switches is provided. Each switch comprises a transmission gate portion, a gate driver portion, a current distribution portion, and a logic enable portion. The transmission gate portion comprises two transistors connected in series source-to-source or drain-to-drain. The gate driver portion detects a voltage at the switch input terminal and the switch output terminal and applies a bias voltage to the gates of the two transistors of the transmission gate portion that is a predetermined amount above a lesser or a greater of the voltage at the switch input terminal or the voltage at the switch output terminal.
