Weighted -Rényi Entropy Power Inequality: Information Theory to Quantum Shannon Theory
Junseo Lee, Hyeonjun Yeo, Kabgyun Jeong
We study the -Rényi entropy power inequality with a weight factor on two independent continuous random variables and . The extension essentially relies on a modulatio…
Simulating Photosynthetic Energy Transport on a Photonic Network
Hao Tang, Xiao-Wen Shang, Zi-Yu Shi +11
Quantum effects in photosynthetic energy transport in nature, especially for the typical Fenna-Matthews-Olson (FMO) complexes, are extensively studied in quantum biology. Such ener…
Random coordinate descent: a simple alternative for optimizing parameterized quantum circuits
Zhiyan Ding, Taehee Ko, Jiahao Yao +2
Variational quantum algorithms rely on the optimization of parameterized quantum circuits in noisy settings. The commonly used back-propagation procedure in classical machine learn…
Mutual information maximizing quantum generative adversarial networks
Mingyu Lee, Myeongjin Shin, Junseo Lee +1
One of the most promising applications in the era of Noisy Intermediate-Scale Quantum (NISQ) computing is quantum generative adversarial networks (QGANs), which offer significant q…
Nondestructive discrimination of Bell states between distant parties
Bohdan Bilash, Youngrong Lim, Hyukjoon Kwon +4
Identifying Bell states without destroying it is frequently dealt with in nowadays quantum technologies such as quantum communication and quantum computing. In practice, quantum en…
Trade-off between Information Gain and Disturbance in Local Discrimination of Entangled Quantum States
Youngrong Lim, Minki Hhan, Hyukjoon Kwon
We establish an information gain-disturbance trade-off relation in local state discrimination. Our result demonstrates a fundamental limitation of local strategy to discriminate en…
