Efficient Quantum Modular Reduction: Crandall reduction and its Fault-tolerant resource analysis

Changyeol Lee, Sungyeon Kook, Wooyeong Song +3

Modular arithmetic is central to quantum algorithms for cryptographic problems, including Shor's algorithm and Grover-based cryptanalysis, with modular reduction contributing subst…

Syndrome-as-Header: A Quantum Label-Switching Architecture via Uncorrectable Error Injection

IlKwon Sohn, Ju-Bong Kim, Kwangil Bae +2

The paper introduces Syndrome-as-Header (SAH), a quantum label‑switching method that embeds routing information in the error‑syndrome of an encoded quantum payload using uncorrecta…

Asymmetry-aided measurement-based quantum repeaters and distributed quantum computing with a decoder-free client

Wooyeong Song, Sungyeon Kook, Wonhyuk Lee +1

The paper proposes using an asymmetric Bacon‑Shor subsystem code as a measurement‑based quantum repeater to transmit logical qubits more efficiently over lossy optical links, and i…

Sharpening Worst-Case Error Assessment for Fault-Tolerant Quantum Computing: Fidelity and Its Deviation

Kyoungho Cho, Ilkwon Sohn, Yongsoo Hwang +1

Gate fidelity -- an average fidelity over all possible input states -- is the workhorse metric for benchmarking quantum gates or circuits, yet fault-tolerant quantum computing ulti…

Fault-tolerant and secure long-distance quantum communication via uncorrectable-error-injection

IlKwon Sohn, Boseon Kim, Kwangil Bae +4

Quantum networks aim to facilitate the fault-tolerant and secure transmission of quantum states across distant devices. The widely adopted quantum teleportation scheme requires mul…

Bounding quantum uncommon information with quantum neural estimators

Donghwa Ji, Junseo Lee, Myeongjin Shin +2

In classical information theory, uncommon information refers to the amount of information that is not shared between two messages, and it admits an operational interpretation as th…
