Silicon quantum dots is one of the most promising quantum computing platforms. After the atomic qubits in silicon have seen tremendous progress in the past 20 years, the next challenge for the atom qubits in silicon is to tailor functional components for scalable quantum computing. Considering the scalable requirements, the hole spin in the Boron atom with EDSR control could be a game-changer. It benefits greatly from the reduced driving component size. Also, using dipole-dipole coupled two qubits could enlarge the qubit footprint and realize a dipole-dipole coupled two-qubit gate. In the end, I am going to outlook the potential methods to build quantum connections between photons and spins in the Boron qubits for a quantum internet. Combined, I will present a blueprint for a scalable atomic silicon chip with those novel quantum gates in Boron qubits.
