Could Non-Baryonic Matter Ever Support Computer Architecture?

Premise

In a world set 10^40 years from now, or in cosmological decade 60 (a cosmological decade is a long term measure of time such that each successive increment represents a ten-fold increase in the total age of the universe), there will be no remnants of cosmological features that are familiar to us except for black holes. As such, this period of time is often referred to as the Black Hole Era. Given that this period takes place in the unfathomably distant future, it will be impossible to speculate about most things, including life. However, it might be safe to say that human life as we know it would not exist during this era, because even protons (or any baryonic particles for that matter) wont be around. Needless to say, organic compounds won't be able to form. What remains are the particles that have no intrinsic mass like photons and electrons.

The world I intend to forge from this apparent apocalyptic setting is one of cyber consciousness. I am trying to devise a means by which an entire civilization can essentially upload their consciousness to some kind of simulation system. Given that the Black Hole Era is very cold, the potential efficiency of the system would be extremely high and could possibly bring salvation to a civilization with a huge population. This is because the computational efficiency of the system would be operating at levels near the Landauer Limit, which might be roughly equivalent to simulating billions of people on 1 watt of power or less. Such efficiency will be needed, as the system will ultimately be fighting a losing battle against the entropy of the universe. Nonetheless, the time span (as well as subjective time at very cold temperatures) of the Black Hole Era will be so long that it would seem like an eternity if such a system could be constructed. This is the presumed motivation -- "eternal" salvation through simulation.

Question: Conceding that very distant events in the future are subjective, is there anything in the (current) laws of physics that explicitly contradicts a computer architecture that is made of entirely non-baryonic matter? If contradictions do exist, please comment on the feasibility of overcoming it through technology. (I hope I don't have to resort to something like a "Heisenberg Compensator")

Further Clarification

• There is very little power available in the Black Hole Era, so the system must run on very low power, a few watts
• 100% non-volatile systems are a plus
• can have no baryonic matter (like protons or neutrons)
