Privacy-preserving quantum federated learning via gradient hiding

no code implementations7 Dec 2023 Changhao Li, Niraj Kumar, Zhixin Song, Shouvanik Chakrabarti, Marco Pistoia

Distributed quantum computing, particularly distributed quantum machine learning, has gained substantial prominence for its capacity to harness the collective power of distributed quantum resources, transcending the limitations of individual quantum nodes.

Analyzing Convergence in Quantum Neural Networks: Deviations from Neural Tangent Kernels

no code implementations26 Mar 2023 Xuchen You, Shouvanik Chakrabarti, Boyang Chen, Xiaodi Wu

In this work, we study the dynamics of QNNs and show that contrary to popular belief it is qualitatively different from that of any kernel regression: due to the unitarity of quantum operations, there is a non-negligible deviation from the tangent kernel regression derived at the random initialization.

Numerical evidence against advantage with quantum fidelity kernels on classical data

no code implementations29 Nov 2022 Lucas Slattery, Ruslan Shaydulin, Shouvanik Chakrabarti, Marco Pistoia, Sami Khairy, Stefan M. Wild

We show that the general-purpose hyperparameter tuning techniques proposed to improve the generalization of quantum kernels lead to the kernel becoming well-approximated by a classical kernel, removing the possibility of quantum advantage.

A Convergence Theory for Over-parameterized Variational Quantum Eigensolvers

no code implementations25 May 2022 Xuchen You, Shouvanik Chakrabarti, Xiaodi Wu

The Variational Quantum Eigensolver (VQE) is a promising candidate for quantum applications on near-term Noisy Intermediate-Scale Quantum (NISQ) computers.

Quantum Machine Learning for Finance

no code implementations9 Sep 2021 Marco Pistoia, Syed Farhan Ahmad, Akshay Ajagekar, Alexander Buts, Shouvanik Chakrabarti, Dylan Herman, Shaohan Hu, Andrew Jena, Pierre Minssen, Pradeep Niroula, Arthur Rattew, Yue Sun, Romina Yalovetzky

In fact, finance is estimated to be the first industry sector to benefit from Quantum Computing not only in the medium and long terms, but even in the short term.

Sublinear classical and quantum algorithms for general matrix games

no code implementations11 Dec 2020 Tongyang Li, Chunhao Wang, Shouvanik Chakrabarti, Xiaodi Wu

We give a sublinear classical algorithm that can interpolate smoothly between these two cases: for any fixed $q\in (1, 2]$, we solve the matrix game where $\mathcal{X}$ is a $\ell_{q}$-norm unit ball within additive error $\epsilon$ in time $\tilde{O}((n+d)/{\epsilon^{2}})$.

On the Principles of Differentiable Quantum Programming Languages

1 code implementation2 Apr 2020 Shaopeng Zhu, Shih-Han Hung, Shouvanik Chakrabarti, Xiaodi Wu

We also conduct a case study of training a VQC instance with controls, which shows the advantage of our scheme over existing auto-differentiation for quantum circuits without controls.

Quantum Wasserstein Generative Adversarial Networks

1 code implementation NeurIPS 2019 Shouvanik Chakrabarti, Yiming Huang, Tongyang Li, Soheil Feizi, Xiaodi Wu

The study of quantum generative models is well-motivated, not only because of its importance in quantum machine learning and quantum chemistry but also because of the perspective of its implementation on near-term quantum machines.

Sublinear quantum algorithms for training linear and kernel-based classifiers

no code implementations4 Apr 2019 Tongyang Li, Shouvanik Chakrabarti, Xiaodi Wu

We design sublinear quantum algorithms for the same task running in $\tilde{O}(\sqrt{n} +\sqrt{d})$ time, a quadratic improvement in both $n$ and $d$.
