In this work, we describe the construction of logic gates NOT, AND, OR, NAND and NOR using superconducting diodes with η≈1 by exploiting their dynamically tunable polarity. We then argue that fundamental theorems suppress η in intrinsic superconductors, rendering them likely unsuitable for the proposed devices, and point out that several previous proposals and platforms, remarkably, bypassed this suppression unwittingly. We discuss the realization of the digital logic in one such platform -- Josephson triodes that yielded η≈1 -- and argue that phases with spontaneous spatial or magnetic order can overcome some of its drawbacks. Thus, this work provides guiding principles for future platforms and develops the building blocks for superconductors-based digital electronics.
