Boosted fusion gates above the percolation threshold for scalable graph-state generation
Yong-Peng Guo, Geng-Yan Zou, Xing Ding +15
Fusing small resource states into a larger, fully connected graph-state is essential for scalable photonic quantum computing. Theoretical analysis reveals that this can only be ach…
Single-photon interference over 8.4 km urban atmosphere: towards testing quantum effects in curved spacetime with photons
Hui-Nan Wu, Yu-Huai Li, Bo Li +8
The emergence of quantum mechanics and general relativity has transformed our understanding of the natural world significantly. However, integrating these two theories presents imm…
Experimental single-photon quantum key distribution surpassing the fundamental coherent-state rate limit
Yang Zhang, Xing Ding, Yang Li +17
Single-photon sources are essential for quantum networks, enabling applications ranging from quantum key distribution (QKD) to the burgeoning quantum internet. Despite the remarkab…
Wavelength-tunable high-fidelity entangled photon sources enabled by dual Stark effects
Chen Chen, Jun-Yong Yan, Hans-Georg Babin +16
The construction of a large-scale quantum internet requires quantum repeaters containing multiple entangled photon sources with identical wavelengths. Semiconductor quantum dots ca…
Experimental quantum non-Gaussian coincidences of entangled photons
Run-Ze Liu, Yu-Kun Qiao, Lukáš Lachman +7
Quantum non-Gaussianity, a more potent and highly useful form of nonclassicality, excludes all convex mixtures of Gaussian states and Gaussian parametric processes generating them.…
