Photon qubits challenge AI, enabling more accurate quantum computing without error-correction techniques

Quantum computing is revolutionizing drug development and material science, with significant advancements made by KIST. Dr. Hyang-Tag Lim's team has developed a quantum algorithm that estimates interatomic bond distances and ground state energies with remarkable accuracy. This achievement eliminates the need for traditional quantum error mitigation techniques, showcasing the potential of quantum computing in practical applications.

The research utilizes a qudit-based approach, allowing for high-dimensional calculations that surpass conventional qubit limitations. By implementing orbital angular momentum states of single photons, the team successfully performed calculations in 16 dimensions, a first in photonic systems. This innovation not only enhances computational efficiency but also opens new avenues for industries reliant on molecular properties.

• KIST achieves chemical accuracy in quantum computing without error mitigation.

• Qudit-based VQE enables high-dimensional calculations in quantum chemistry.
