Polynomial-time algorithm for simulation of weakly interacting quantum spin systems
Sergey Bravyi, David DiVincenzo, Daniel Loss
We describe an algorithm that computes the ground state energy and correlation functions for 2-local Hamiltonians in which interactions between qubits are weak compared to single-q…

Highly Entangled Ground States in Tripartite Qubit Systems
Beat Röthlisberger, Jörg Lehmann, D. S. Saraga +2
We investigate the creation of highly entangled ground states in a system of three exchange-coupled qubits arranged in a ring geometry. Suitable magnetic field configurations yield…
