High-fidelity geometric quantum gates exceeding 99.9% in germanium quantum dots
Yu-Chen Zhou, Rong-Long Ma, Zhenzhen Kong +11
Achieving high-fidelity and robust qubit manipulations is a crucial requirement for realizing faulttolerant quantum computation. Here, we demonstrate a single-hole spin qubit in a…
High Mobility SiGe/Ge 2DHG Heterostructure Quantum Wells for Semiconductor Hole Spin Qubits
Zhenzhen Kong, Zonghu Li, Yuchen Zhou +11
Strong spin-orbit coupling and relatively weak hyperfine interactions make germanium hole spin qubits a promising candidate for semiconductor quantum processors. The two-dimensiona…
Singlet-triplet-state readout in silicon-metal-oxide-semiconductor double quantum dots
Rong-Long Ma, Sheng-Kai Zhu, Zhen-Zhen Kong +9
High-fidelity singlet-triplet state readout is essential for large-scale quantum computing. However, the widely used threshold method of comparing a mean value with the fixed thres…
Ultrafast and Electrically Tunable Rabi Frequency in a Germanium Hut Wire Hole Spin Qubit
He Liu, Ke Wang, Fei Gao +9
Hole spin qubits based on germanium (Ge) have strong tunable spin orbit interaction (SOI) and ultrafast qubit operation speed. Here we report that the Rabi frequency (f_Rabi) of a…
