研究室紹介
Professor Ki-Eung Kim's research lab specializes in quantum information science and technology, with a focus on advancing the security and efficiency of quantum communication systems. The lab investigates novel quantum key distribution protocols, particularly those leveraging multi-qubit encoding schemes using polarization, phase, and frequency modulations to enhance secrecy and system performance. A key research direction involves analyzing and deriving theoretical bounds for quantum symbol error rates under incoherent attacks, contributing to the practical implementation of secure quantum networks. The lab also explores the integration of quantum optics with classical communication infrastructures to enable scalable and robust quantum technologies.

1The tolerance bound for quantum symbol error rate in a multi-qubit quantum key distribution system is derived in consideration of an incoherent attack on a single-photon quantum channel, where multi-qubit encoding and measurement can be applied to a single photon in combination of polarization, phase, and frequency modulations. This paper presents a solid theoretical evidence of a multiqubit gain in secrecy performance.
