The New Quantum Era

A peer-reviewed paper in PNAS predicts Shor's algorithm will fail at a few hundred error-corrected qubits — not from engineering limits, but because Hilbert space itself may be subtly wrong. Oxford's Tim Palmer argues quantum mechanics should be built on rational numbers, not the continuum.

It's an interesting idea. As thermalization is fundamentally a process of spreading entanglement, I would think that this theory would imply some limit to the degree to which subsystems can thermalize and thus violations of thermodynamic laws.
