Einstein-Podolsky-Rosen Energy-Time Entanglement of Narrowband Biphotons
Yefeng Mei, Yiru Zhou, Shanchao Zhang +5
We report the direct characterization of energy-time entanglement of narrowband biphotons produced from spontaneous four-wave mixing in cold atoms. The Stokes and anti-Stokes two-p…
Note on "Experimental Measurement of Quantum Metric Tensor and Related Topological Phase Transition with a Superconducting Qubit"
Yan-Qing Zhu, Dan-Wei Zhang, Xinsheng Tan +4
In the paper [X. Tan et al., Phys. Rev. Lett. 122, 210401 (2019)], we have studied the Euler characteristic number for a two-band model; However, the calculated there is no…
Non-Hermitian Topological Anderson Insulators
Dan-Wei Zhang, Ling-Zhi Tang, Li-Jun Lang +2
Non-Hermitian systems can exhibit unique topological and localization properties. Here we elucidate the non-Hermitian effects on disordered topological systems by studying a non-He…
Experimental Measurement of the Quantum Metric Tensor and Related Topological Phase Transition with a Superconducting Qubit
Xinsheng Tan, Dan-Wei Zhang, Zhen Yang +12
Berry curvature is an imaginary component of the quantum geometric tensor (QGT) and is well studied in many branches of modern physics; however, the quantum metric as a real compon…
-Quench measurement of quantum wavefunction
Shanchao Zhang#, Yiru Zhou#, Yefeng Mei# +7
Measurement of quantum state wavefunction not only acts as a fundamental part in quantum physics but also plays an important role in developing practical quantum technologies. Conv…
