Effect of disorder and strain on the operation of planar Ge hole spin qubits

Abhikbrata Sarkar, Pratik Chowdhury, Xuedong Hu +5

Germanium quantum dots in strained $\text{Ge}/{\text{Si}}_{1-x}{\text{Ge}}_x$ heterostructures exhibit fast and coherent hole qubit control in experiments. In this work, we theoretic…
