Hamiltonian-reconstruction distance as a success metric for the Variational Quantum Eigensolver

Leo Joon Il Moon, Mandar M. Sohoni, Michael A. Shimizu +4

The Variational Quantum Eigensolver (VQE) is a hybrid quantum-classical algorithm for quantum simulation that can be run on near-term quantum hardware. A challenge in VQE -- as wel…

Dominant 1/3-filling Correlated Insulator States and Orbital Geometric Frustration in Twisted Bilayer Graphene

Haidong Tian, Emilio Codecido, Dan Mao +8

Geometric frustration is a phenomenon in a lattice system where not all interactions can be satisfied, the simplest example being antiferromagnetically coupled spins on a triangula…
