Quantum Algorithms for Boolean Equation Solving and Quantum Algebraic Attack on Cryptosystems
Yu-Ao Chen, Xiao-Shan Gao
Decision of whether a Boolean equation system has a solution is an NPC problem and finding a solution is NP hard. In this paper, we present a quantum algorithm to decide whether a…
New bounds of Mutually unbiased maximally entangled bases in C^d\otimes C^{kd}
Xiaoya Cheng, Yun Shang
Mutually unbiased bases which is also maximally entangled bases is called mutually unbiased maximally entangled bases (MUMEBs). We study the construction of MUMEBs in bipartite sys…
Quantum gate identification: error analysis, numerical results and optical experiment
Yuanlong Wang, Qi Yin, Daoyi Dong +5
The identification of an unknown quantum gate is a significant issue in quantum technology. In this paper, we propose a quantum gate identification method within the framework of q…
Approximate broadcasting of quantum correlations
Wei Xie, Kun Fang, Xin Wang +1
Broadcasting quantum and classical information is a basic task in quantum information processing, and is also a useful model in the study of quantum correlations including quantum…
Learning-based Quantum Robust Control: Algorithm, Applications and Experiments
Daoyi Dong, Xi Xing, Hailan Ma +3
Robust control design for quantum systems has been recognized as a key task in quantum information technology, molecular chemistry and atomic physics. In this paper, an improved di…
Indistinguishability of bipartite states by positive-partial-transpose operations in the many-copy scenario
Yinan Li, Xin Wang, Runyao Duan
A bipartite subspace is called strongly positive-partial-transpose-unextendible (PPT-unextendible) if for every positive integer , there is no PPT operator supporting on the…
