Controlled-Z gate for transmon qubits coupled by semiconductor junctions
Zhenyi Qi, Hong-Yi Xie, Javad Shabani +3
We analyze the coupling of two qubits via an epitaxial semiconducting junction. In particular, we consider three configurations that include pairs of transmons or gatemons as well…

Effects of charge noise on a pulse-gated singlet-triplet qubit
Zhenyi Qi, X. Wu, D. R. Ward +11
We study the dynamics of a pulse-gated semiconductor double quantum dot qubit. In our experiments, the qubit coherence times are relatively long, but the visibility of the quantum…
