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…
Annual-modulation fingerprint of the axion wind induced sideband triplet in quantum dot spin qubit sensors
Xiangjun Tan, Zhanning Wang
We propose a phase-coherent, narrowband magnetometer for searching couplings between axions or axion-like particles (ALPs) and electron spins, using gate-defined silicon quantum-do…
Toward Axion Signal Extraction in Semiconductor Spin Qubits Via Spectral Engineering
Xiangjun Tan, Zhanning Wang
Recent advances in quantum sensing and computational technologies indicate the possibility of improving the precision of measurements aimed at detecting cosmological particles and…
