计算布尔平均值的平均情况量子下界

Average case quantum lower bounds for computing the boolean mean

A. Papageorgiou

摘要:

我们研究了布尔平均的平均情况近似的量子算法。我们证明了一般的查询下界类的概率措施的一组输入。我们特别注意两个概率,在那里我们显示特定的查询和错误下限和实现它们的算法。我们还研究了量子算法的最坏期望误差和平均期望误差,并给出了相应的查询下界。我们的研究结果扩展了最优性的算法Escherard等人。

英文摘要:

We study the average case approximation of the Boolean mean by quantum algorithms. We prove general query lower bounds for classes of probability measures on the set of inputs. We pay special attention to two probabilities, where we show specific query and error lower bounds and the algorithms that achieve them. We also study the worst expected error and the average expected error of quantum algorithms and show the respective query lower bounds. Our results extend the optimality of the algorithm of Brassard et al.
