Covertness as a resource constraint in quantum target sensing
Yu Yang, Fengyu Guan, Shiping Guo +3
Quantum covert target sensing aims to detect low-reflectivity targets embedded in the thermal environment while avoiding discovery by an adversary. This covertness requirement cons…
Efficient quantum state tomography with auxiliary Hilbert space
Ruifeng Liu, Junling Long, Pei Zhang +4
Quantum state tomography is an important tool for quantum communication, computation, metrology, and simulation. Efficient quantum state tomography on a high dimensional quantum sy…
Demonstration of quantum permutation algorithm with a single photon ququart
Feiran Wang, Yunlong Wang, Ruifeng Liu +4
We report an experiment to demonstrate a quantum permutation determining algorithm with linear optical system. By employing photon polarization and spatial modes, we realize the qu…
Super sub-wavelength patterns in photon coincidence detection
Ruifeng Liu, Pei Zhang, Yu Zhou +2
High-precision measurements implemented by means of light is desired in all fields of science. However, light is a wave and Rayleigh criterion gives us a diffraction limitation in…
Deutsch's algorithm with topological charges of optical vortices via non-degenerate four-wave mixing
Mingtao Cao, Liang Han, Ruifeng Liu +8
We propose a scheme to implement the Deutsch's algorithm through non-degenerate four-wave mixing process. By employing photon topological charges of optical vortices, we demonstrat…
Implementing the Deutsch's algorithm with spin-orbital angular momentum of photon without interferometer
Pei Zhang, Yan Jiang, Rui-Feng Liu +3
Deutsch's algorithm is the simplest quantum algorithm which shows the acceleration of quantum computer. In this paper, we theoretically advance a scheme to implement quantum Deutsc…
