  We consider a device which allows to create and probe single Majorana
fermions, in the form of Bogoliubov quasiparticles. It is composed of two
counter-propagating edge channels, each put in proximity with a superconducting
region where Andreev reflection operates, and which thus converts electrons
into Bogoliubov quasiparticles. The edge channels then meet at a quantum point
contact where collisions can be achieved. A voltage biased version of the setup
was studied in Phys. Rev. Lett. 112, 070604 (2014) and showed non-local
interference phenomena and signatures of Bogoliubov quasiparticle collisions in
the high frequency noise characteristics at the output, constituting an
evidence of the Majorana fermion nature of these excitations. Here, voltage
biased leads are replaced by single electron sources in order to achieve
collisions of single Bogoliubov quasiparticles, with the major advantage that
zero-frequency noise measurements are sufficient to access the intimate nature
of Bogoliubov wave-packets. We compute the injection parameters of the source,
and go on to investigate the Hanbury-Brown and Twiss and Hong-Ou-Mandel signal
at the output, as a function of the mixing angle which controls the
electron/hole component of the Bogoliubov wave-packet. In particular,
information on the internal structure of the Bogoliubov quasiparticle can be
recovered when such a quasiparticle collides with a pure electron. Experimental
feasibility with singlet or triplet superconductors is discussed.
