Bell, group and tangle

Solomon, Allan (2010). Bell, group and tangle. Physics of Atomic Nuclei, 73(3) pp. 524–533.



The “Bell” of the title refers to bipartite Bell states, and their extensions to, for example, tripartite systems. The “Group” of the title is the Braid Group in its various representations; while “Tangle” refers to the property of entanglement which is present in both of these scenarios. The objective of this note is to explore the relation between Quantum Entanglement and Topological Links, and to show that the use of the language of entanglement in both cases is more than one of linguistic analogy.
