Selection of the configuration of the cross-section of a multi-flue stacks with four inner flues of different diameters

open access: yesИзвестия высших учебных заведений: Проблемы энергетики, 2023
Despite the widespread use of single-flue stacks, due to the possibility of increasing the rise of flue gases into the atmosphere due to the close location of individual flues in a common shell and ensuring the high reliability of this shell by isolating

Looped Pipelines Enabling Effective 3D Qubit Lattices in a Strictly 2D Device

open access: yesPRX Quantum, 2023
Many quantum computing platforms are based on a two-dimensional (2D) physical layout. Here we explore a concept called looped pipelines, which permits one to obtain many of the advantages of a three-dimensional (3D) lattice while operating a strictly 2D ...
