Generalized reduction criterion for separability of quantum states
A new necessary separability criterion that relates the structures of the
total density matrix and its reductions is given. The method used is based on
the realignment method [K. Chen and L.A. Wu, Quant. Inf. Comput. 3, 193
(2003)]. The new separability criterion naturally generalizes the reduction
separability criterion introduced independently in previous work of [M.
Horodecki and P. Horodecki, Phys. Rev. A 59, 4206 (1999)] and [N.J. Cerf, C.
Adami and R.M. Gingrich, Phys. Rev. A 60, 898 (1999)]. In special cases, it
recovers the previous reduction criterion and the recent generalized partial
transposition criterion [K. Chen and L.A. Wu, Phys. Lett. A 306, 14 (2002)].
The criterion involves only simple matrix manipulations and can therefore be
easily applied.Comment: 17 pages, 2 figure
