A Codebook Design for FD-MIMO Systems with Multi-Panel Array
Zhilin Fu, Sangwon Hwang, Jihwan Moon +2
In this work, we study codebook designs for full-dimension multiple-input multiple-output (FD-MIMO) systems with a multi-panel array (MPA). We propose novel codebooks which allow p…
Quantifying non-Gaussianity of a quantum state by the negative entropy of quadrature distributions
Jiyong Park, Jaehak Lee, Kyunghyun Baek +1
We propose a non-Gaussianity measure of a multimode quantum state based on the negentropy of quadrature distributions. Our measure satisfies desirable properties as a non-Gaussiani…
Sequential Feature Filtering Classifier
Minseok Seo, Jaemin Lee, Jongchan Park +1
We propose Sequential Feature Filtering Classifier (FFC), a simple but effective classifier for convolutional neural networks (CNNs). With sequential LayerNorm and ReLU, FFC zeroes…
Quantum non-Gaussianity and secure quantum communication
Jaehak Lee, Jiyong Park, Hyunchul Nha
No-cloning theorem, a profound fundamental principle of quantum mechanics, also provides a crucial practical basis for secure quantum communication. The security of communication c…
Defects responsible for abnormal n-type conductivity in Ag-excess doped PbTe thermoelectrics
Byungki Ryu, Min-Wook Oh, Jae Ki Lee +6
We find that Ag-interstitial () acts as an electron donor and plays an important role in Ag-excess doped polycrystalline PbTe thermoelectric materials. When Ag is heavily dop…
