Method for Simulating and Evaluating an Electronic System
Quantum mechanical systems, such as for instance electronic states in molecules or solid bodies, can be simulated using quantum computers. However, at present quantum computers only provide a limited quantity of qubits for the calculation. This deficiency is attributable to unsolved problems in connection with inherent noise and scalability, with the result that quantum computers currently only enable simulations of small quantum systems.
A method simulates and evaluates an electronic system with a continuous spectral density on the basis of the interruption of the quantum simulation by measurements. The quantum simulation is interrupted to read the qubits, the qubit measurements are stored in a classical parity register and restored to the qubits, and the simulation is continued after the restore.
