Quantum coherence: Maintaining quantum coherence over larger scales could allow for more complex quantum computations.
Zero-point energy: Some speculative theories suggest harnessing zero-point energy for computation, though this remains highly theoretical.
Quantum error correction: Advanced quantum error correction techniques would be crucial for maintaining computational integrity at quantum scales.
Computational requirements for Computronium:
The computational capacity of computronium is theoretically immense, approaching physical limits of computation. To quantify this:
- Bremermann's limit: This theoretical limit suggests a maximum computational speed of about 1.36 × 10^50 bits per second per kilogram of mass.
