Radio frequency readout and control of Ge/SiGe hole spin qubits with a global accumulation gate
Tien-Ho Chang, Chi-Wei Lee, Jian-Chang Zeng +12
Hole spin qubits in undoped Ge/SiGe quantum well structures have advanced rapidly in performance and scalability. However, stringent multi-layer patterning and overlay requirements…
Ge hole spin control using acoustic waves
Chun-Yang Yuan, Tzu-Kan Hsiao
Germanium hole spin qubits based on strained Ge/SiGe quantum well have attracted much research attention due to the strong spin-orbit coupling. In particular, the strain dependence…
Site-resolved magnon and triplon dynamics on a programmable quantum dot spin ladder
Pablo Cova Fariña, Daniel Jirovec, Xin Zhang +7
Quasi-particle dynamics in interacting systems in the presence of disorder challenges the notion of internal thermalization, but proves difficult to investigate theoretically for l…
Universal control of four singlet-triplet qubits
Xin Zhang, Elizaveta Morozova, Maximilian Rimbach-Russ +9
The coherent control of interacting spins in semiconductor quantum dots is of strong interest for quantum information processing as well as for studying quantum magnetism from the…
