Dismantling the Stoquastic Dichotomy
Armen Karakashian, Itay Hen
We challenge the notion that a stoquastic binary governs fundamental computational boundaries in quantum computing and classical simulation of quantum systems. We argue that vanish…

Stoquasticity is not enough: towards a sharper diagnostic for Quantum Monte Carlo simulability
Arman Babakhani, Armen Karakashian
Quantum Monte Carlo (QMC) methods are powerful tools for simulating quantum many-body systems, yet their applicability is limited by the infamous sign problem. We approach this cha…
