Quantum Cut Sparsifiers
Arpon Basu, Joshua Brakensiek, Pravesh K. Kothari +1
In this paper, we continue a line of research initiated by Basu, Brakensiek, and Putterman [2026] studying the sparsifiability of Hamiltonians. We focus particularly on the sparsif…

Many Hamiltonians Are Sparsifiable
Arpon Basu, Joshua Brakensiek, Aaron Putterman
We study the problem of Hamiltonian sparsification: given a parameter and an -qubit Hamiltonian which is the sum of -local positive semi-definite…
