The Complexity of the Consistency and N-representability Problems for Quantum States
Yi-Kai Liu
QMA (Quantum Merlin-Arthur) is the quantum analogue of the class NP. There are a few QMA-complete problems, most notably the ``Local Hamiltonian'' problem introduced by Kitaev. In…

Consistency of Local Density Matrices is QMA-complete
Yi-Kai Liu
Suppose we have an n-qubit system, and we are given a collection of local density matrices rho_1,...,rho_m, where each rho_i describes a subset C_i of the qubits. We say that the r…

Gibbs States and the Consistency of Local Density Matrices
Yi-Kai Liu
Suppose we have an n-qubit system, and we are given a collection of local density matrices rho_1,...,rho_m, where each rho_i describes some subset of the qubits. We say that rho_1,…
