Abstract
In recent years, germanium hole spin qubits have become a research hotspot for semiconductor quantum dot quantum computing. Their strong spin-orbit coupling gives rise to an anisotropic exchange interaction. The exchange interaction plays an important role in implementing two-qubit gates for electron/hole spin qubits. Currently, the modeling, control, and optimization of exchange interaction primarily focus on the isotropic type between electron spins. Strategies for making full use of the anisotropic exchange interaction to implement high-fidelity two-qubit gates remain immature. In this thesis, we focus on germanium hole spin qubits and utilize the anisotropic exchange interaction between them to implement two-qubit gates protected against errors by means of composite pulse technique.
