A note on tomography of states with low stabilizer rank

Arkopal Dutt

In this note, we consider tomography of -qubit quantum states that are promised to have stabilizer rank i.e., admit a stabilizer decomposition of $|ψ\rangle = \s…

Marton's conjecture in polynomial time

Srinivasan Arunachalam, Arkopal Dutt, Sabee Grewal +1

Gowers, Green, Manners, and Tao (Annals '25) recently resolved Marton's polynomial Freiman-Ruzsa conjecture. We give an algorithmic counterpart to their result: given uniform sampl…

Quantum simulation of non-Markovian dynamical systems

Abtin Ameri, Arkopal Dutt, Hari Krovi

Existing quantum algorithms for simulating dynamical systems -- from Hamiltonian simulation to linear and nonlinear differential equations solvers -- simulate Markovian dynamics, i…

Learning Clifford-structured quantum unitaries and Hamiltonians

Arkopal Dutt, Dale Jacobs, John Jeang +2

Learning algorithms for structured quantum unitaries and Hamiltonians have primarily considered classes of processes that are local or sparse in the Pauli basis. We turn our attent…

Separating quantum circuits from classical LLMs

Srinivasan Arunachalam, Arkopal Dutt, Hari Krovi +1

Modern large language models - transformers and diffusion language models - are built around two canonical algorithmic tasks: prediction and generation. We prove unconditional sepa…

Tomography of quantum states with bounded extent

Srinivasan Arunachalam, Arkopal Dutt

We give a general framework for tomography of states that have bounded-extent with respect to a structured class of states. Let be a family of -qubit states such th…

Simulating dynamics of RLC circuits with a quantum differential-algebraic equations solver

Arkopal Dutt, Anirban Chowdhury, Kristan Temme +1

We introduce a quantum algorithm for simulating the dynamics of electrical circuits consisting of resistors, inductors and capacitors (aka RLC circuits) along with power sources. G…

An algorithmic Polynomial Freiman-Ruzsa theorem

Davi Castro-Silva, Jop Briët, Srinivasan Arunachalam +2

We provide algorithmic versions of the Polynomial Freiman-Ruzsa theorem of Gowers, Green, Manners, and Tao (Ann. of Math., 2025). In particular, we give a polynomial-time algorithm…
