Are there any quantum particles created at the centre of the earth and if so are there any of those particles able to make it to the surface of the earth and fly out into space.

There should be some beta decays occurring down there, that would emit (anti)neutrinos that could escape the earth.

well, there's a whole bunch of quarks, gluons and electrons down there. its possible that they will eventually reach the surface through a volcano or something but far more likely when the sun blows up and major parts of the earth vapourize.
