If I am reading this right, this could lead to quantum computers that are literally nuclear powered! (specifically by radioactive cobalt-57 ) . Please would someone correct me if I got that bit wrong.

The generation of the 14.4 Mev photons come from the cobalt/iron 57 but that is all, just the basic generation of photons. There is no indication of an actual use of the energy except for the subsequent processing of the photon for quantum purposes but they say it will be useful at room temperature.

They also mention the difficulty of using these high energy photons with normal optics so a lot of new technology will have to be invented in order to actualize new devices.

So this is a fundamental development only and only time will tell if this can be developed into something useful outside the scientific usefulness of being able to have a new way to study quantum effects.

The rest of the circuitry will be powered normally, through photonics or electronics, they won't be generating energy with the cobalt/iron 57 so it seems to me.
