High-Fidelity Hole Spin Qubits Reveal Quadrupolar Nuclear-Bath Dynamics in Isotopically Purified Planar Germanium
Jian Zeng, Xiangjun Tan, Hongzhang Wang +10
Planar Germanium has emerged as a promising platform to build spin-based large scale quantum computers. By exploiting the anisotropic hyperfine interaction of holes in Ge, qubits w…
Quantum Error Correction Assisted Axion Search in CMOS Spin Qubit Arrays
Xiangjun Tan, Zhanning Wang
Searches for axion and axionlike dark matter based on solid-state spin qubits are fundamentally limited by strong longitudinal dephasing, which rapidly suppresses the sensitivity g…
Axion signal search using hybrid nuclear-electronic spin systems
Xiangjun Tan, Zhanning Wang
Conventional nuclear magnetic resonance searches for the galactic axion wind lose sensitivity at low frequencies due to the unfavourable scaling of inductive readout. Here, we prop…
Cancelling second order frequency shifts in Ge hole spin qubits via bichromatic control
Xiangjun Tan, Zhanning Wang, Wenkai Bai +1
Germanium quantum dot hole spin qubits are compatible with fully electrical control and are progressing toward multi-qubit operations. However, their coherence is limited by charge…
