Robust implementation of quantum gates despite always-on exchange coupling in silicon double quantum dots
Utkan Güngördü, J. P. Kestner
Addressability of spin qubits in a silicon double quantum dot setup in the (1,1) charge configuration relies on having a large difference between the Zeeman splittings of the elect…

Pulse sequence designed for robust C-phase gates in SiMOS and Si/SiGe double quantum dots
Utkan Güngördü, J. P. Kestner
We theoretically analyze the errors in one- and two-qubit gates in SiMOS and Si/SiGe spin qubit experiments, and present a pulse sequence which can suppress the errors in exchange…
