Non-perturbative gadget for topological quantum codes
Samuel A. Ocko, Beni Yoshida
Many-body entangled systems, in particular topologically ordered spin systems proposed as resources for quantum information processing tasks, often involve highly non-local interac…

Quantum codes give counterexamples to the unique pre-image conjecture of the N-representability problem
Samuel A. Ocko, Xie Chen, Bei Zeng +4
It is well known that the ground state energy of many-particle Hamiltonians involving only 2-body interactions can be obtained using constrained optimizations over density matrices…
