We've already had discussions about anti-matter being used as a fuel
one day, but typically there were criticisms about the stability of the
magnetic bottles used to contain the anti-matter.

Here is an article about positronium as a possible future power source:

So if positronium could be stored at low-temperature and low-density as
a Bose-Einstein Condensate, then could it be harnessed as a high-energy
power source for a launch vehicle?

store BECs can be small enough to fit in the palm of your hand. I'm not
sure if electron-positron anihilation can be harnessed in such a way so
as to control the direction in which the resulting high-energy photons
are emitted, but if that were possible then wouldn't it reduce the need
for radioactive shielding around your power source?
