SYSTEMS AND METHODS FOR SIMULATION OF QUANTUM CIRCUITS USING DECOUPLED HAMILTONIANS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240013082 titled 'SYSTEMS AND METHODS FOR SIMULATION OF QUANTUM CIRCUITS USING DECOUPLED HAMILTONIANS
Simplified Explanation
Methods and techniques are provided for simulating a quantum circuit. The system can perform operations such as generating a transformed Hamiltonian corresponding to the quantum circuit. The transformed Hamiltonian includes transformed local and coupling Hamiltonians. The generation of the transformed Hamiltonian involves obtaining a charge coupling matrix and a flux coupling matrix of an original Hamiltonian corresponding to the quantum circuit. The charge coupling matrix and the flux coupling matrix are at least partially diagonalized.
The operations further include determining a limited eigenbasis consisting of a number of eigenvectors of the transformed local Hamiltonian. The transformed coupling Hamiltonian and the transformed local Hamiltonian are projected onto the limited eigenbasis. An at least partially decoupled Hamiltonian is generated by combining the projection of the transformed coupling and local Hamiltonians. The operations also include simulating the behavior of the quantum circuit using the at least partially decoupled Hamiltonian.
