Quantum Codes Give Counterexamples to the Unique Preimage Conjecture of the N-Representability Problem
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 which arise from reducing an N-particle state. While determining which 2-particle density matrices are “N-representable...
