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…
In-plane optimal qubit operation with control fidelities exceeding 99 %
Yu-Chen Zhou, Zhenzhen Kong, Rong-Long Ma +9
Hole spin qubits based on semiconductor quantum dots are promising for building future large-scale quantum computers owing to their all-electrical manipulation. However, abundant p…
On-chip Parametric Amplification in a Double Quantum Dots Circuit
Yong-Qiang Xu, Rui Wu, Si-Si Gu +8
In microwave-based quantum circuits, including double quantum dots (DQDs), superconducting qubits and spin qubits, parametric amplifiers are indispensable in achieving high-fidelit…
Cryogenic interface-state filling and tunneling mechanisms in strained Ge/SiGe heterostructures
Jingrui Ma, Yuan Kang, Rui Wu +11
Traps at the semiconductor-oxide interface are considered as a major source of instability in strained Ge/SiGe quantum devices, yet the quantified study of their cryogenic behavior…
