Measurement-Protected Quantum Key Distribution
Spiros Kechrimparis, Heasin Ko, Young-Ho Ko +5
In the distribution of quantum states over a long distance, not only are quantum states corrupted by interactions with an environment but also a measurement setting should be re-al…
Quantum secure learning with classical samples
Wooyeong Song, Youngrong Lim, Hyukjoon Kwon +5
Studies addressing the question "Can a learner complete the learning securely?" have recently been spurred from the standpoints of fundamental theory and potential applications. In…
Quantum solvability of noisy linear problems by divide-and-conquer strategy
Wooyeong Song, Youngrong Lim, Kabgyun Jeong +5
Noisy linear problems have been studied in various science and engineering disciplines. A class of "hard" noisy linear problems can be formulated as follows: Given a matrix $\hat{A…
Tangible reduction in learning sample complexity with large classical samples and small quantum system
Wooyeong Song, Marcin Wieśniak, Nana Liu +4
Quantum computation requires large classical datasets to be embedded into quantum states in order to exploit quantum parallelism. However, this embedding requires considerable reso…
