  • A Complete Set of Invariants for LU-Equivalence of Density Operators 
    Turner, J.; Morton, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2017)
    We show that two density operators of mixed quantum states are in the same local unitary orbit if and only if they agree on polynomial invariants in a certain Noetherian ring for which degree bounds are known in the ...
  • Algebraic Geometry of Matrix Product States 
    Critch, A.; Morton, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2014)
    We quantify the representational power of matrix product states (MPS) for entangled qubit systems by giving polynomial expressions in a pure quantum state's amplitudes which hold if and only if the state is a translation ...
