Semidefinite programming relaxations have been\r\nfruitful in designing theoretical approximation algorithms for QMC, but are\r\ncomputationally expensive for systems beyond tens of qubits. We give a second\r\norder cone relaxation for QMC, which optimizes over the set of mutually\r\nconsistent three-qubit reduced density matrices. In combination with Pauli\r\nlevel-$1$ of the quantum Lasserre hierarchy, the relaxation achieves an\r\napproximation ratio of $0.526$ to the ground state energy. Our relaxation is\r\nsolvable on systems with hundreds of qubits and paves the way to\r\ncomputationally efficient lower and upper bounds on the ground state energy of\r\nlarge-scale quantum spin systems.","lang":"eng"}],"user_id":"71541"}
