Channel-loss-independent quantum-enhanced interferometer
Yi-Xin Shen, Zhou-Kai Cao, Jian Leng +1
We propose a channel-loss-independent quantum-enhanced interferometer. In our scheme, the Fisher information for phase difference of weak light from a remote star remains constant…
Piecemeal method revisited
Yi-Xin Shen, Zhou-Kai Cao, Jian Leng +1
Detecting the angles and orbits of remote targets precisely has been playing crucial roles in astrophysical research. Due to the resolution limitations imposed by the Airy disk in…
Piecemeal Telescope Array: Exponential Precision with Strong Robustness and High Efficiency
Jian Leng, Yi-Xin Shen, Zhou-Kai Cao +1
Optical telescopes are powerful eyes for terrestrial and astronomical detection. Here we propose a new detection method with high efficiency, strong robustness and super precision,…
Quantum Advantage of Noisy Grover's Algorithm
Jian Leng, Fan Yang, Xiang-Bin Wang
Quantum advantage is the core of quantum computing. Grover's search algorithm is the only quantum algorithm with proven advantage to any possible classical search algorithm. Howeve…
Modifying -qubit controlled- gate to be -qubit Toffoli gate
Jian Leng, Fan Yang, Xiang-Bin Wang
The decomposition for controlled- gate in [Phys. Rev. A, 87, 062318 (2013)] has a shallow circuit depth with no ancilla. Here we modify this decomposition to decompose…
Improving D2p Grover's algorithm to reach performance upper bound under phase noise
Jian Leng, Fan Yang, Xiang-Bin Wang
The original Grover's algorithm has a success probability to output a correct solution, while deterministic Grover's algorithms improve the success probability to 100%. However, th…
