GIST Professor Ham Byeongseung Proposes New Interpretation of Core Principles in Quantum Mechanics

[Asia Economy Honam Reporting Headquarters Reporter Park Jin-hyung] Professor Ham Byung-seung of GIST, a leading scholar in the field of quantum memory, announced on the 13th that he has published a paper in an international journal presenting a new interpretation of the origin of nonlocal quantum correlations in quantum entanglement pairs, one of the core principles of quantum mechanics.

Nonlocal quantum correlations have been experimentally proven perfectly over the past half-century, but since the principle of single-photon pair generation itself has been shrouded in mystery, the quantum correlations based on it could not be fully understood, which was a limitation of the existing quantum academic community.

Professor Ham provided a wave-based interpretation with phase information for the quantum entanglement phenomenon, which is intuitively difficult to understand because phase information cannot be determined by the conventional complementary particle nature in quantum mechanics. This not only makes it easy to understand entangled photon pairs but also establishes an academic foundation that can be materially implemented.

In existing quantum information research, the mysterious nature of entangled pairs, which are the core principle, has been veiled, but now a definitive understanding similar to classical information is required.

According to the current quantum mechanical interpretation of quantum entanglement pairs, it has been impossible to deterministically create entangled qubit pairs at a desired time, and there have been serious limitations in the scalability of qubits, which are the material information units in quantum information.

In other words, to enable information processing with a single execution as in classical information, the primitive and probabilistic quantum information basis must be changed to a deterministic basis.

Furthermore, according to the existing theory based on complementary particle nature, phase control between qubits is practically impossible, leaving inevitable coherence loss acceleration among multiple qubits uncontrollable.

Contrary to the mainstream interpretation in the existing quantum academic community, Professor Ham interpreted quantum ground pairs as waves and identified the principle by which quantum entanglement can be deterministically implemented using a general laser. As a specific implementation method, he proposed ‘Franson nonlocal quantum correlation’ based on classical coherence, newly establishing the foundation of a macroscopic quantum worldview.

Professor Ham explained, “Based on the wave interpretation of light, we clarified the understanding of the previously veiled single-photon pair generation and, based on this, revealed the origin of nonlocal quantum correlations in entangled photon pairs.” He added, “We expect this research result to clarify the understanding of nonlocal quantum correlations and ultimately serve as the foundation for future quantum information communication technologies compatible with currently used optical devices and optical communication technologies.”

This research was conducted with the support of the Ministry of Science and ICT’s ITRC Quantum Internet project and was published in the online edition of AVS Quantum Science.
