On-chip integration of Si/SiGe-based quantum dots and electronic circuits for scaling

With continuous breakthroughs in quantum science and technology in recent years, the development of quantum computers is moving from pure scientific research to engineering realization. Meanwhile, the underlying physical structures also develop from the initial single qubit to multiple qubits or medium-scale qubit registers. Since qubits are operated by many sophisticated instruments under strict environmental conditions, people need a scalable solution to support many qubits working at the same time, so as to achieve high computing speed for a practical quantum computer.QCD/Vandersypen La
