    "abstract": "Entangling an unknown qubit with one type of reference state is generally\nimpossible. However, entangling an unknown qubit with two types of reference\nstates is possible. To achieve this, we introduce a new class of states called\nzero sum amplitude (ZSA) multipartite, pure entangled states for qubits and\nstudy their salient features. Using shared-ZSA state, local operation and\nclassical communication we give a protocol for creating multipartite entangled\nstates of an unknown quantum state with two types of reference states at remote\nplaces. This provides a way of encoding an unknown pure qubit state into a\nmultiqubit entangled state. We quantify the amount of classical and quantum\nresources required to create universal entangled states. This is possibly a\nstrongest form of quantum bit hiding with multiparties.",
