Measuring quantum geometric tensor of non-Abelian system in superconducting circuits
Wen Zheng, Jianwen Xu, Zhuang Ma +11
Topology played an important role in physics research during the last few decades. In particular, the quantum geometric tensor that provides local information about topological pro…
Improve photon number discrimination for a superconducting series nanowire detector by applying a digital matched filter
Hao Hao, Qing-Yuan Zhao, Ling-Dong Kong +15
Photon number resolving (PNR) is an important capacity for detectors working in quantum and classical applications. Although a conventional superconducting nanowire single-photon d…
Heterogeneously integrated, superconducting silicon-photonic platform for measurement-device-independent quantum key distribution
Xiaodong Zheng, Peiyu Zhang, Renyou Ge +10
Integrated photonics provides a route both to miniaturize quantum key distribution (QKD) devices and to enhance their performance. A key element for achieving discrete-variable QKD…
Simulating the Kibble-Zurek mechanism of the Ising model with a superconducting qubit system
Ming Gong, Xueda Wen, Guozhu Sun +11
The Kibble-Zurek mechanism (KZM) predicts the density of topological defects produced in the dynamical processes of phase transitions in systems ranging from cosmology to condensed…
Noncollinear parametric fluorescence by chirped quasi-phase matching for monocycle temporal entanglement
Akira Tanaka, Ryo Okamoto, Hwan Hong Lim +9
Quantum entanglement of two photons created by spontaneous parametric downconversion (SPDC) can be used to probe quantum optical phenomena during a single cycle of light. Harris [P…
Landau-Zener-Stuckelberg interferometry in multilevel superconducting flux qubit
Xueda Wen, Yiwen Wang, Shanhua Cong +7
Landau-Zener-Stuckelberg interferometry has been extensively investigated in quantum two-level systems, with particular interests on artificial system such as superconducting flux…
