Physics: Probing the Planck Scale
To achieve computing that operates at or tests the physics of the Planck scale, a system must challenge the “classical limit” of one operation per Planck volume-time (2⁴⁹¹ operations per cubic meter per second). According to groundbreaking quantum gravity research, this requires: [1]
Planck Energy-Level Dynamics: Operating at the Planck length requires handling the Planck energy (10¹⁹ GeV). At this threshold, packing energy into such a tiny space creates microscopic black holes that instantly decay via Hawking radiation, meaning the computer would need to manipulate spacetime geometry itself.
A Minimum of 500 to 1,600 Logical Qubits: A highly stable quantum computer with at least 500 error-corrected, logical qubits is mathematically sufficient to reject classical, localized physics theories and directly probe Planck-scale quantum gravity effects. [1]
A Theory of Quantum Gravity: We currently lack a unified framework combining General Relativity and Quantum Mechanics. Designing algorithms for this scale requires finalized math from String Theory, Loop Quantum Gravity, or holographic spacetime models. [1, 2]
