Research results on the Fourier space readout (FSR) method for efficiently recovering functions encoded in quantum states have been published in the journal Quantum Science and Technology.
Quemix, in collaboration with Sumitomo Rubber Industries, Ltd., proposed a quantum-classical hybrid method to address the readout problem that arises when quantum computers are applied to computer-aided engineering and related computations. The method obtains the dominant Fourier coefficients of a continuous function encoded in a quantum state on a quantum computer and reconstructs the function on a classical computer.
Theoretical analysis and numerical experiments showed that the computational cost on the quantum computer scales logarithmically with the number of grid points, while the computational cost on the classical computer scales with the number of target points to be reconstructed rather than the total number of grid points. These results indicate that quantum speedups for CAE problems may be preserved during the readout process.
