Understanding quantum algorithms via query complexity

A Ambainis - Proceedings of the International Congress of …, 2018 - World Scientific
Query complexity is a model of computation in which we have to compute a function f (x 1,…,
x N) of variables xi which can be accessed via queries. The complexity of an algorithm is …

Learning low-degree quantum objects

S Arunachalam, A Dutt, FE Gutiérrez… - arxiv preprint arxiv …, 2024 - arxiv.org
We consider the problem of learning low-degree quantum objects up to $\varepsilon $-error
in $\ell_2 $-distance. We show the following results: $(i) $ unknown $ n $-qubit degree-$ d …

Constant matters: Fine-grained Complexity of Differentially Private Continual Observation

H Fichtenberger, M Henzinger, J Upadhyay - arxiv preprint arxiv …, 2022 - arxiv.org
We study fine-grained error bounds for differentially private algorithms for counting under
continual observation. Our main insight is that the matrix mechanism when using lower …

[PDF][PDF] Quantum and classical query complexities of functions of matrices

A Montanaro, C Shao - Proceedings of the 56th Annual ACM …, 2024 - dl.acm.org
Let A be an s-sparse Hermitian matrix, f (x) be a univariate function, and i, j be two indices. In
this work, we investigate the query complexity of approximating if (A) j. We show that for any …

application of quantum algorithms, covering aspects of supervised, unsupervised and …

Influence in completely bounded block-multilinear forms and classical simulation of quantum algorithms

N Bansal, M Sinha, R de Wolf - arxiv preprint arxiv:2203.00212, 2022 - arxiv.org
The Aaronson-Ambainis conjecture (Theory of Computing'14) says that every low-degree
bounded polynomial on the Boolean hypercube has an influential variable. This conjecture …

Characterization of exact one-query quantum algorithms

W Chen, Z Ye, L Li - Physical Review A, 2020 - APS
The quantum query model is one of the most important models in quantum computing.
Several well-known quantum algorithms are captured by this model, including the Deutsch …
