Qubit-qudit states with positive partial transpose
Lin Chen, Dragomir Z. Djokovic
We show that the length of a qubit-qutrit separable state is equal to the max(r,s), where r is the rank of the state and s is the rank of its partial transpose. We refer to the ord…

Dimensions, lengths and separability in finite-dimensional quantum systems
Lin Chen, Dragomir Z. Djokovic
Many important sets of normalized states in a multipartite quantum system of finite dimension d, such as the set S of all separable states, are real semialgebraic sets. We compute…

Equivalence classes and canonical forms for two-qutrit entangled states of rank four having positive partial transpose
Lin Chen, Dragomir Z. Djokovic
Let E' denote the set of non-normalized two-qutrit entangled states of rank four having positive partial transpose (PPT). We show that the set of SLOCC equivalence classes of state…
