Spatial nonlocality imaging via metasurface
Jian Li, Zi-Mu Fan, Qing-Yuan Wu +7
Bell nonlocality is both a defining signature of entanglement and a key quantum information resource. However, visualizing and certifying nonlocal correlations across a spatially m…
Prescriptive preparation and verification of nonstabilizer states
Jian Li, Ye-Chao Liu, Xiao-Xiao Chen +6
High-fidelity quantum state preparation is a central task in quantum information science. In practice, it is commonly guided either by full quantum state tomography, which becomes…
Experimental realization of universal high-dimensional quantum gates with ultra-high fidelity and efficiency
Zhe Meng, Wen-Qiang Liu, Bo-Wen Song +3
Qudit, a high-dimensional quantum system, provides a larger Hilbert space to process the quantum information and has shown remarkable advantages over the qubit counterparts. It is…
Experimentally demonstrating indefinite causal order algorithms to solve the generalized Deutsch's problem
Wen-Qiang Liu, Zhe Meng, Bo-Wen Song +6
Deutsch's algorithm is the first quantum algorithm to show the advantage over the classical algorithm. Here we generalize Deutsch's problem to functions and propose a new quant…
Nonclassical oscillations in pre- and post-selected quantum walks
Xiaoxiao Chen, Zhe Meng, Jian Li +4
Quantum walks are counterparts of classical random walks. They spread faster, which can be exploited in information processing tasks, and constitute a versatile simulation platform…
