The Laminar Architecture of Visual Cortex and Image Processing Technology [PDF]

, 1999
The mammalian neocortex is organized into layers which include circuits that form functional columns in cortical maps. A major unsolved problem concerns how bottom-up, top-down, and horizontal interactions are organized within cortical layers to generate

Digital-analog quantum algorithm for the quantum Fourier transform

Physical Review Research, 2020
Quantum computers will allow calculations beyond existing classical computers. However, current technology is still too noisy and imperfect to construct a universal digital quantum computer with quantum error correction.
