*We define generalised notions of biunitary elements in planar algebras and
show that there is a one-one correspondence between certain objects arising
in quantum information theory and some biunitary elements in the spin
planar algebra . Also we show that there are natural subfactor planar
algebras associated with these biunitary elements. Finally we will identify
the planar algebras associated with Latin squares with the subgroup-group
planar algebras.
