Saving resources through repeat-until-success positive-operator-valued-measure measurements in quantum computation
Hefeng Wang, Sixia Yu, Hua Xiang
We present a quantum computation approach in which computation is guided by positive-operator-valuedmeasure (POVM) measurements following a given computation path in multisteps. In…
Quantum algorithm for PageRank computation through multistep quantum resonant transitions
Chuqing Wang, Hefeng Wang, Hua Xiang
We present a quantum algorithm for obtaining a quantum state that encodes the PageRank vector of the Google matrix through multistep quantum resonant transition (mQRT). In the algo…
Quantum optimization algorithm based on multistep quantum computation
Hefeng Wang, Hua Xiang
We present a quantum algorithm for finding the minimum of a function based on multistep quantum computation and apply it for optimization problems with continuous variables, in whi…
Efficient quantum algorithms for solving quantum linear system problems
Hefeng Wang, Hua Xiang
We transform the problem of solving linear system of equations to a problem of finding the right singular vector with singular value zero of an augmented m…
Polynomial-time quantum algorithm for solving the hidden subgroup problem
Hefeng Wang
The hidden subgroup problem~(HSP) is one of the most important problems in quantum computation. Many problems for which quantum algorithm achieves exponential speedup over its clas…
Efficient quantum algorithm for solving structured problems via multi-step quantum computation
Hefeng Wang, Sixia Yu, Hua Xiang
In classical computation, a problem can be solved in multiple steps where calculated results of each step can be copied and used repeatedly. While in quantum computation, it is dif…
