Speeding up the classical simulation of Gaussian boson sampling with limited connectivity
Tian-Yu Yang, Xiang-Bin Wang
Gaussian Boson sampling (GBS) plays a crucially important role in demonstrating quantum advantage. As a major imperfection, the limited connectivity of the linear optical network w…
Twin-field quantum key distribution with local frequency reference
Jiu-Peng Chen, Fei Zhou, Chi Zhang +9
Twin-field quantum key distribution (TF-QKD) overcomes the linear rate-loss limit, which promises a boost of secure key rate over long distance. However, the complexity of eliminat…
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…
Side-channel-secure quantum key distribution
Cong Jiang, Xiao-Long Hu, Zong-Wen Yu +1
We present a result of side-channel-secure (SCS) quantum key distribution (QKD) under fully realistic conditions. Our result is not only measurement-device independent but also eff…
