Report

The group symmetries inherent in quantum channels often make them tractable and applicable to various problems in quantum information theory. In this paper, we introduce natural probability distributions for covariant quantum channels. Specifically,

$k$-positivity and Schmidt number under orthogonal group symmetries

Autor: Park, Sang-Jun, Youn, Sang-Gyun

In this paper, we study $k$-positivity and Schmidt number under standard orthogonal group symmetries. The Schmidt number is a natural quantification of entanglement in quantum information theory. First of all, we exhibit a complete characterization o

Generation of Structurally Realistic Retinal Fundus Images with Diffusion Models

Autor: Go, Sojung, Ji, Younghoon, Park, Sang Jun, Lee, Soochahn

We introduce a new technique for generating retinal fundus images that have anatomically accurate vascular structures, using diffusion models. We generate artery/vein masks to create the vascular structure, which we then condition to produce retinal

A universal framework for entanglement detection under group symmetry

Autor: Park, Sang-Jun, Jung, Yeong-Gwang, Park, Jeongeun, Youn, Sang-Gyun

One of the most fundamental questions in quantum information theory is PPT-entanglement of quantum states, which is an NP-hard problem in general. In this paper, however, we prove that all PPT $(\overline{\pi}_A\otimes \pi_B)$-invariant quantum state

The Bibliographic studies on Scolopendra subspinipes mutilans L. Koch

Autor: Go, Gang-Hun, So, Gi-Suk, Choe, Hoe-Gang, O, Hui-Hong, Kim, Il-Du, Park, Sang-Jun, An, Su-Gi, Kim, Seong-Cheol, Park, So-Yeong

Publikováno v: Journal of Pharmacopuncture, Vol 5, Iss 1, Pp 53-59 (2002)

Objective: Through the literature on the effect of Scolopendra subspinipes mutilans L. Koch, we are finding out the clinical possibility and revealing the more effective to untractable disease. Method: We investigated the literatures of Oriental Medi

Gaussian quantum information over general quantum kinematical systems I: Gaussian states

Autor: Beny, Cedric, Crann, Jason, Lee, Hun Hee, Park, Sang-Jun, Youn, Sang-Gyun

We develop a theory of Gaussian states over general quantum kinematical systems with finitely many degrees of freedom. The underlying phase space is described by a locally compact abelian (LCA) group $G$ with a symplectic structure determined by a 2-
