    "abstract": "We present a generalized partial transposition separability criterion for the\ndensity matrix of a multipartite quantum system. This criterion comprises as\nspecial cases the famous Peres-Horodecki criterion and the recent realignment\ncriterion in [O. Rudolph, quant-ph/0202121] and [K. Chen, L.A. Wu,\nquant-ph/0205017]. It involves only straightforward matrix manipulations and is\neasy to apply. A quantitative measure of entanglement based on this criterion\nis also obtained.",
