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…
Phonon-assisted transport and hole-phonon coupling in GaAs double quantum dots
Jin Leng, Wei-Zhu Liao, Hao-Tian Jiang +5
Hole-phonon interactions play an important role in transport and decoherence processes in semiconductor quantum dots. Here we investigate hole-phonon coupling in a gate-defined GaA…
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…
