In particular quantum computation, the subject of this lecture, is not modeled correctly by any of the above. But there are eve ...

Optimal parallel quantum query algorithms
... queries. Recently, Belovs gave a o(n3/4 )-query algorithm for k-distinctness for any fixed k [8] (which can also be made time-efficient for k = 3 [11]). In contrast, Ambainis’s O(nk/(k+1) )-query algorithm is optimal for k-sum [10, 14]. Here we consider to what extent such algorithms can be parallel ...
