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…
Designing generalized elegant Bell inequalities in higher dimensions from a Tsirelson bound
Kwangil Bae, Junghee Ryu, Ilkwon Sohn +1
Elegant Bell inequality is well known for its distinctive property, being maximally violated by maximal entanglement, mutually unbiased bases, and symmetric informationally complet…
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…
Structural encoding with classical codes for computational-basis bit-flip correction in the early fault-tolerant regime
IlKwon Sohn, Changyeol Lee, Wooyeong Song +2
Achieving reliable performance on early fault-tolerant quantum hardware will depend on protocols that manage noise without incurring prohibitive overhead. We propose a novel framew…
Enhanced Extrapolation-Based Quantum Error Mitigation Using Repetitive Structure in Quantum Algorithms
Boseon Kim, Wooyeong Song, Kwangil Bae +2
Quantum error mitigation is a crucial technique for suppressing errors especially in noisy intermediate-scale quantum devices, enabling more reliable quantum computation without th…
