Optimal Distributed quantum sensing using Gaussian states
Changhun Oh, Changhyoup Lee, Seok Hyung Lie +1
We find and investigate the optimal scheme of quantum distributed Gaussian sensing for estimation of the average of independent phase shifts. We show that the ultimate sensitivity…

Randomness cost of masking quantum information and the information conservation law
Seok Hyung Lie, Hyunseok Jeong
Masking quantum information, which is impossible without randomness as a resource, is a task that encodes quantum information into bipartite quantum state while forbidding local pa…

Quantum one-time tables for unconditionally secure qubit-commitment
Seok Hyung Lie, Hyukjoon Kwon, M. S Kim +1
The commodity-based cryptography is an alternative approach to realize conventionally impossible cryptographic primitives such as unconditionally secure bit-commitment by consuming…
