An exact Error Threshold of Surface Code under Correlated Nearest-Neighbor Errors: A Statistical Mechanical Analysis
SiYing Wang, ZhiXin Xia, Yue Yan +1
The surface code represents a promising candidate for fault-tolerant quantum computation due to its high error threshold and experimental accessibility with nearest-neighbor intera…
The practical issues of side-channel-secure quantum key distribution
Cong Jiang, Xiao-Long Hu, Zong-Wen Yu +2
Quantum Key Distribution (QKD) leverages the principles of quantum mechanics to provide theoretically unconditional security for cryptographic key sharing. However, practical imple…
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…
Symmetry in Multi-Qubit Correlated Noise Errors Enhances Surface Code Thresholds
SiYing Wang, Yue Yan, ZhiXin Xia +1
Surface codes are promising for practical quantum error correction due to their high threshold and experimental feasibility. However, their performance under realistic noise condit…
Experimental Multi-Dimensional Side-Channel-Secure Quantum Key Distribution
Hao Dong, Cong Jiang, Di Ma +8
Quantum key distribution (QKD) theoretically provides unconditional security between remote parties. However, guaranteeing practical security through device characterisation alone…
Warm Start Adaptive-Bias Quantum Approximate Optimization Algorithm
Yunlong Yu, Xiang-Bin Wang, Nic Shannon +1
In the search for quantum advantage in real--world problems, one promising avenue is to use a quantum algorithm to improve on the solution found using an efficient classical algori…
