This paper presents the parastatistics of braided Majorana fermions obtained in the framework of a graded Hopf algebra endowed with a braided tensor product. The braiding property is encoded in a $t$-dependent $4\times 4$ braiding matrix $B_t$ related to the Alexander-Conway polynomial. The nonvanishing complex parameter $t$ defines the braided parastatistics. At $t=1$ ordinary fermions are recovered. The values of $t$ at roots of unity are organized into levels which specify the maximal number of braided Majorana fermions in a multiparticle sector. Generic values of $t$ and the $t=-1$ root of unity mimick the behaviour of ordinary bosons.

Author comments upon resubmission
following your request of a minor revision I have inserted a paragraph
explaining why the Z_2-graded qubits describe Majorana fermions.
Two extra references ( and ) have been added with respect
to the previous version.
List of changes
A paragraph (4 lines) has been added after formula (3) at page 2:
from “The excited state is a Majorana …”
till “ … (implying that the charge conjugation operator is the identity).”
Two extra references ( and ) have been added.
