FGFRFT: Fast Graph Fractional Fourier Transform via Exact Spectral Splitting and Fourier-Series Approximation
Ziqi Yan, Mingzhi Wang, Sen Shi +4
The graph fractional Fourier transform (GFRFT) for unitary graph Fourier transform (GFT) matrices can be interpreted through the scalar function on the unit circle. Under…
Spin Polarization Control via Magnetic Field in Dissipative Bosonic Systems
Yaoyuan Fan, Shuoyu Shi, Lang Cao +4
Engineering spin polarization in dissipative bosonic systems is crucial for advancing quantum technologies, especially for applications in quantum metrology and space-based quantum…
Adaptive cold-atom magnetometry mitigating the trade-off between sensitivity and dynamic range
Zhu Ma, Chengyin Han, Zhi Tan +7
Cold-atom magnetometers can achieve an exceptional combination of superior sensitivity and high spatial resolution. One key challenge these quantum sensors face is improving the se…
Machine learning topological energy braiding of non-Bloch bands
Shuwei Shi, Shibing Chu, Yuee Xie +1
Machine learning has been used to identify phase transitions in a variety of physical systems. However, there is still a lack of relevant research on non-Bloch energy braiding in n…
