A Study on the Error Aspects of Conjunctive Adverbs of Korean Learning Chinese Native Users: To middle and high-level learners
2019
The study polled 17 access agencies on 62 intermediate-level, 100 high-level, and 162 university-level Korean learners in China to identify the error patterns of connecting Korean. The survey found that the errors of ‘causal, confrontational-positive, …

Hacking single-photon avalanche detectors in quantum key distribution via pulse illumination
2020 · Optics Express
Quantum key distribution (QKD) has been proved to be information-theoretically secure in theory. Unfortunately, the imperfect devices in practice compromise its security. Thus, to improve the security property of practical QKD systems, a commonly used …

Quantum memory assisted entangled state verification with local measurements
2025 · Physical Review Research
We consider the quantum memory assisted quantum state verification task, where an adversary prepares independent multipartite entangled states and sends them to the local verifiers, who then store several copies in the quantum memory and …

High-efficiency Weak-trace-free Counterfactual Communication via Quantum Zeno Effect
2025 · arXiv (Cornell University)
The quantum Zeno effect, which inhibits quantum state evolution via repeated weak measurements, significantly enhances the efficiency of interaction-free measurement (IFM). This fundamental mechanism facilitates high-efficiency counterfactual quantum communication, enabling information delivery without particle transmission …

Deep Cut-informed Graph Embedding and Clustering
2025 · arXiv (Cornell University)
Graph clustering aims to divide the graph into different clusters. The recently emerging deep graph clustering approaches are largely built on graph neural networks (GNN). However, GNN is designed for general graph encoding and there …

Distributed quantum inner product estimation with structured random circuits
2026 · npj Quantum Information
Distributed inner product estimation (DIPE) is a fundamental task in quantum information, aiming to estimate the inner product between two unknown quantum states prepared on distributed quantum platforms. Existing rigorous sample complexity analyses are limited …
