The various embodiments pertain to extracting one or more noiseless configurations from a collection of noisy configurations generated by a quantum processor. A configuration can be represented as a series of bits, 1's and 0's, whereby 1 indicates a spin orbital is occupied and 0 indicates spin orbital is empty. Noise in the quantum system can cause a respective bit to be flipped from a 0 to a 1, and vice-versa.

After bit flipping, a Hamiltonian diagonalization process can be applied to the noiseless configuration to generate an eigenstate from which a ground state of the system represented by the noisy configuration can be determined. The system can be an atom or molecule, with the bits relating to a spin orbital of an electron.

The invention introduces a Total Wave structure of the Modified Schrödinger Equation (MSE) that deterministically governs quantum collapse using co-evolving field-specific wave-functions. Unlike conventional quantum mechanics, which treats wavefunction collapse as a postulated or probabilistic phenomenon, this invention models collapse as a structured outcome of wave interference from multiple physical fields—electromagnetic, gravitational, strong nuclear, and weak nuclear—each governed by its own nonlinear MSE.The system wavefunction Ψp evolves under the influence of these field-specific observer waves Ψj, and collapse occurs when the total interference term exceeds a defined threshold. This model supports not only collapse but also resonance (sub-threshold wave alignment) and non-collapse (persistent superposition), forming a tri-state mechanism of existence.The Total Wave MSE formalism applies to quantum hardware design, computation, sensing, and AI-guided control. By treating collapse as an engineered interference event, the invention enables deterministic reality selection across multiple domains. It extends the scope of earlier MSE patents and proposes that this structure represents a scalable, tunable, and physically grounded Theory of Everything (TOE).
