Quantum linear algebra is all you need for Transformer architectures

no code implementations26 Feb 2024 Naixu Guo, Zhan Yu, Matthew Choi, Aman Agrawal, Kouhei Nakaji, Alán Aspuru-Guzik, Patrick Rebentrost

Generative machine learning methods such as large-language models are revolutionizing the creation of text and images.

Quantum Algorithms for the Pathwise Lasso

no code implementations21 Dec 2023 Joao F. Doriguello, Debbie Lim, Chi Seng Pun, Patrick Rebentrost, Tushar Vaidya

Finally, we propose a dequantised algorithm that also retains the polylogarithmic dependence on $n$, albeit with the linear scaling on $d$ from the standard LARS algorithm.

Post-variational quantum neural networks

no code implementations20 Jul 2023 Po-Wei Huang, Patrick Rebentrost

Hybrid quantum-classical computing in the noisy intermediate-scale quantum (NISQ) era with variational algorithms can exhibit barren plateau issues, causing difficult convergence of gradient-based optimization techniques.

Robust quantum minimum finding with an application to hypothesis selection

no code implementations26 Mar 2020 Yihui Quek, Clement Canonne, Patrick Rebentrost

We demonstrate a quantum algorithm for noisy quantum minimum-finding that preserves the quadratic speedup of the noiseless case: our algorithm runs in time $\tilde O(\sqrt{N (1+\Delta)})$, where $\Delta$ is an upper-bound on the number of elements within the interval $\alpha$, and outputs a good approximation of the true minimum with high probability.

Our classical result improves on the algorithm of [CLSW17] and runs in time $\widetilde{O}(n^{3/2}/\epsilon^2 \cdot \mathrm{EO})$.

Quantum principal component analysis

no code implementations1 Jul 2013 Seth Lloyd, Masoud Mohseni, Patrick Rebentrost

The usual way to reveal properties of an unknown quantum state, given many copies of a system in that state, is to perform measurements of different observables and to analyze the measurement results statistically.
