Assessing the potential of Ge/SiGe quantum dots as hosts for singlet-triplet qubits

Andrea Hofmann, Daniel Jirovec, Maxim Borovkov +6

We study double quantum dots in a Ge/SiGe heterostructure and test their maturity towards singlet-triplet ($S-T_0$) qubits. We demonstrate a large range of tunability, from two sin…
