WebBeside this, GHZ states maximize entanglement monotones and therefore can be called maximally entangled in multipartite sense. Moreover GHZ states belong to the states for which the normal form coincides with the particular state. For example in the case of three qubits there is only one such state and this is exactly the GHZ state. Web1 jul. 2024 · A scheme for the multihop non-destructive teleportation of an arbitrary single-qudit state based on various non-maximally entangled Greenberger–Horne–Zeilinger channels is proposed here. The parallel entanglement swap is used to form a direct d -dimensional ( d ≥ 2 ) entangled channel shared between the sender and the receiver.
