Abstract: We propose a deterministic protocol for remotely preparing an arbitrary four-qubit entangled cluster-type state. In our protocol, a seven-qubit cluster state is employed to link the two senders (Alice and Bob) and the receiver Charlie.…

Abstract: We present a new scheme to provide an arbitrary four-photon polarization-entangled state, which enables the encoding of single logical qubit information into a four-qubit decoherence-free subspace robustly against collective decoherence. With the assistance of the…

Abstract: High-dimensional entanglement is a valuable resource for secure and efficient quantum information processing. A major challenge for practical use of multidimensional quantum systems is the establishment of controls over arbitrary superposition states in realistic conditions.…
