An outstanding proposal is a simple setup which probabilistically fuses two W states of arbitrary sizes n >= 3 and m >= 3, creating a W state of size n + m - 2 (Ozdemir et al., in: New J Phys 13:103003, 2011). Using this setup as building blocks, we propose a new setup which can fuse four W states simultaneously. The proposed setup can fuse W states of size 2, i.e. Bell states, as well. We study the resource cost of our fusion process for two main scenarios, i.e. starting from sizes 2 and 3. We present some cost efficient cases, as compared to the previous work.eninfo:eu-repo/semantics/closedAccessW state fusionMultipartite entanglementQuantum networksArticleQ1Q212929652975WOS:000322728200003
