Assessing the potential of Ge/SiGe quantum dots as hosts for singlet-triplet qubits Hofmann, Andrea C Jirovec, Daniel ; https://orcid.org/0000-0002-7197-4801 Borovkov, Maxim Prieto Gonzalez, Ivan ; https://orcid.org/0000-0002-7370-5357 Ballabio, Andrea Frigerio, Jacopo Chrastina, Daniel Isella, Giovanni Katsaros, Georgios ; https://orcid.org/0000-0001-8342-202X 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 single quantum dots to a double quantum dot. We measure Pauli spin blockade and study the anisotropy of the $g$-factor. We use an adjacent quantum dot for sensing charge transitions in the double quantum dot at interest. In conclusion, Ge/SiGe possesses all ingredients necessary for building a singlet-triplet qubit. 2019 info:eu-repo/semantics/preprint doc-type:Preprint Preprint http://purl.org/coar/resource_type/c_816b https://research-explorer.ista.ac.at/record/10065 Hofmann AC, Jirovec D, Borovkov M, et al.
