Real classical shadows
Maxwell West, Antonio Anna Mele, Martin Larocca +1
Efficiently learning expectation values of a quantum state using classical shadow tomography has become a fundamental task in quantum information theory. In a classical shadows pro…
Analyzing the quantum approximate optimization algorithm: ansätze, symmetries, and Lie algebras
Sujay Kazi, Martín Larocca, Marco Farinati +3
The Quantum Approximate Optimization Algorithm (QAOA) has been proposed as a method to obtain approximate solutions for combinatorial optimization tasks. In this work, we study the…
Random ensembles of symplectic and unitary states are indistinguishable
Maxwell West, Antonio Anna Mele, Martin Larocca +1
A unitary state -design is an ensemble of pure quantum states whose moments match up to the -th order those of states uniformly sampled from a -dimensional Hilbert space.…
Classical shadows with symmetries
Frederic Sauvage, Martin Larocca
Classical shadows (CS) have emerged as a powerful way to estimate many properties of quantum states based on random measurements and classical post-processing. In their original fo…
Gate-based quantum simulation of Gaussian bosonic circuits on exponentially many modes
Alice Barthe, M. Cerezo, Andrew T. Sornborger +2
We introduce a framework for simulating, on an -qubit quantum computer, the action of a Gaussian Bosonic (GB) circuit on a state over modes. Specifically, we encode th…
Quantum Algorithms for Representation-Theoretic Multiplicities
Martin Larocca, Vojtech Havlicek
Kostka, Littlewood-Richardson, Plethysm and Kronecker coefficients are the multiplicities of irreducible representations in the decomposition of representations of the symmetric gr…
