Exact quantum lower bound for grover's problem
One of the most important quantum algorithms ever discovered is Grover’s algorithm for searching an unordered set. We give a new lower bound in the query model which proves that Grover’s algorithm is exactly optimal. Similar to existing methods for proving lower bounds, we bound the amount of information we can gain from a single oracle query, but we bound this information in terms of angles. T...
متن کاملQuantum Lower Bound for the Collision Problem with Small Range
We extend Aaronson and Shi’s quantum lower bound for the r-to-one collision problem. An r-to-one function is one where every element of the image has exactly r preimages. The r-to-one collision problem is to distinguish between one-to-one functions and r-to-one functions over an n-element domain. Recently, Aaronson and Shi proved a lower bound of Ω((n/r)1/3) quantum queries for the r-to-one col...
متن کاملQuantum lower bound for sorting ∗
Needless to say, sorting, especially sorting by comparisons, has been a classical problem in computer science. Despite its enormous importance, the complexity, in terms of the number of comparisons needed, is simple to analyze. Straightforward information theoretical argument gives the tight lower bound of log2(n!), which is achieved by several simple sorting algorithms, for example, Insertion ...
متن کاملA New Lower Bound for Flexible Flow Shop Problem with Unrelated Parallel Machines
Flexible flow shop scheduling problem (FFS) with unrelated parallel machines contains sequencing in flow shop where, at any stage, there exists one or more processors. The objective consists of minimizing the maximum completion time. Because of NP-completeness of FFS problem, it is necessary to use heuristics method to address problems of moderate to large scale problem. Therefore, for assessme...
متن کاملQuantum lower bound for recursive fourier sampling
We revisit the oft-neglected ‘recursive Fourier sampling’ (RFS) problem, introduced by Bernstein and Vazirani to prove an oracle separation between BPP and BQP. We show that the known quantum algorithm for RFS is essentially optimal, despite its seemingly wasteful need to uncompute information. This implies that, to place BQP outside of PH [log] relative to an oracle, one needs to go outside th...
