Characterization, synthesis, and optimization of quantum circuits over multiple-control -rotation gates: A systematic study
Shihao Zhang, Junda Wu, Lvzhou Li
We conduct a systematic study of quantum circuits composed of multiple-control -rotation (MCZR) gates as primitives, since they are widely-used components in quantum algorithms…
Automatic Depth-Optimized Quantum Circuit Synthesis for Diagonal Unitary Matrices with Asymptotically Optimal Gate Count
Shihao Zhang, Kai Huang, Lvzhou Li
Current noisy intermediate-scale quantum (NISQ) devices can only execute small circuits with shallow depth, as they are still constrained by the presence of noise: quantum gates ha…
Quantum Algorithms for Identifying Hidden Strings with Applications to Matroid Problems
Xiaowei Huang, Shihao Zhang, Lvzhou Li
In this paper, we explore quantum speedups for the problem, inspired by matroid theory, of identifying a pair of -bit binary strings that are promised to have the same number of…
Quantum algorithm for learning secret strings and its experimental demonstration
Yongzhen Xu, Shihao Zhang, Lvzhou Li
In this paper, we consider the secret-string-learning problem in the teacher-student setting: the teacher has a secret string , and the student wants to learn t…
Efficient composite pulse sequences for arbitrarily accurate z-axis rotation gates
Li Zhang, Shihao Zhang
We propose various composite -pulse sequences for implementing robust z-axis rotation gates widely used in quantum information processing (QIP) scenarios, and discuss their erro…
