A first basis is rotated to render part of the Hamiltonian diagonal, then the quantum processor evolves backwards until a value s* of the normalized evolution coefficient. Another basis is rotated to render another part of the Hamiltonian diagonal and the quantum processor evolves backwards again until s*. The bases can be rotated via discrete Fourier transform. The quantum processor may pause for a time t after each backward evolution. The ground state energy is calculated using the final ground states."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for calculating the ground state of non-diagonal Hamiltonians","description":"A hybrid computing system comprising a digital and an analog processor calculates the ground energy state of a non-diagonal Hamiltonian via diagonalization of the Hamiltonian in different bases and re","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11481354","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
