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 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…
