Experimental Test of Tracking the King Problem
Cheng-Qiu Hu, Jun Gao, Lu-Feng Qiao +7
In quantum theory, the retrodiction problem is not as clear as its classical counterpart because of the uncertainty principle of quantum mechanics. In classical physics, the measur…
Transmission of Photonic Polarization States through 55-meter Water: Towards Air-to-sea Quantum Communication
Cheng-Qiu Hu, Zeng-Quan Yan, Jun Gao +9
Quantum communication has been rapidly developed due to its unconditional security and successfully implemented through optical fibers and free-space air in experiment. To build a…
Topological Protection of Two-photon Quantum Correlation on a Photonic Chip
Yao Wang, Xiao-Ling Pang, Yong-Heng Lu +4
Low-decoherence regime plays a key role in constructing multi-particle quantum systems and has therefore been constantly pursued in order to build quantum simulators and quantum co…
Reconstruction of the Real Quantum Channel via Convex Optimization
Xuan-Lun Huang, Jun Gao, Zhi-Qiang Jiao +3
Quantum process tomography is often used to completely characterize an unknown quantum process. However, it may lead to an unphysical process matrix, which will cause the loss of i…
Quantum Topological Boundary States in Quasi-crystal
Yao Wang, Yong-Heng Lu, Jun Gao +4
Topological phase, a novel and fundamental role in matter, displays an extraordinary robustness to smooth changes in material parameters or disorder. A crossover between topologica…
Integrated Server for Measurement-Device-Independent Quantum Key Distribution Network
Ci-Yu Wang, Jun Gao, Zhi-Qiang Jiao +8
Quantum key distribution (QKD), harnessing quantum physics and optoelectronics, may promise unconditionally secure information exchange in theory. Recently, theoretical and experim…
Experimental Quantum Fast Hitting on Hexagonal Graphs
Hao Tang, Carlo Di Franco, Zi-Yu Shi +9
Quantum walks are powerful kernels in quantum computing protocols that possess strong capabilities in speeding up various simulation and optimisation tasks. One striking example is…
Mapping and Measuring Large-scale Photonic Correlation with Single-photon Imaging
Ke Sun, Jun Gao, Ming-Ming Cao +10
Quantum correlation and its measurement are essential in exploring fundamental quantum physics problems and developing quantum enhanced technologies. Quantum correlation may be gen…
Mapping Twisted Light into and out of a Photonic Chip
Yuan Chen, Jun Gao, Zhi-Qiang Jiao +6
Twisted light carrying orbital angular momentum (OAM) provides an additional degree of freedom for modern optics and an emerging resource for both classical and quantum information…
Parity-Induced Thermalization Gap in Disordered Ring Lattices
Yao Wang, Jun Gao, Xiao-Ling Pang +8
The gaps separating two different states widely exist in various physical systems: from the electrons in periodic lattices to the analogs in photonic, phononic, plasmonic systems,…
