- Abstract summary: A device based on coupled spins capable of generating and sharing out an entangled pair of qubits is presented.
Three different entangling protocols were proposed for this chain in [1] and [2].
Here we compare the robustness of such protocols against different types of fabrication (static energy fluctuations) and operation (timing injection delays) errors.

- Abstract: In this contribution we consider an advantageous building block with
potential for various quantum applications: a device based on coupled spins
capable of generating and sharing out an entangled pair of qubits. Our model
device is a dimerised spin chain with three weakly coupled embedded sites
(defects). Three different entangling protocols were proposed for this chain in
[1] and [2], one producing a Cluster state and two generating a Bell state,
depending on the initial state injection. Here we compare the robustness of
such protocols as quantum entangling gates against different types of
fabrication (static energy fluctuations) and operation (timing injection
delays) errors.
