Local Invariants for a Class of Mixed States
arXiv:quant-ph/0505156 · doi:10.1016/j.physleta.2005.04.005
Abstract
We investigate the equivalence of quantum states under local unitary transformations. A complete set of invariants under local unitary transformations is presented for a class of mixed states. It is shown that two states in this class are locally equivalent if and only if all these invariants have equal values for them.
