Abstract:
We introduce a physically motivated classification of pure quantum states describing n qubits. We characterize all multipartite states which can be maximally entangled to local auxiliary systems using controlled operations. A state has this property if and only if one can construct out of it an orthonormal basis by applying independent local unitary operations. This implies that those states can be used to encode locally the maximum amount of n independent bits. Examples of these states are the...     »
