Reversible Computing
A computing architecture theory in which chips are designed to perform reversible logical operations that do not discard information, enabling the recovery of energy that would otherwise dissipate as heat and thereby reducing power consumption at the level of fundamental physical principles.

Reversible computing is not a new concept; its theoretical foundations were established decades ago.
Vaire Computing is building a new-architecture chip that improves energy efficiency by recovering energy that would otherwise be wasted as heat.
The core idea of reversible computing is to design logical operations in which information is not discarded, allowing every computational step to be reversed, thereby eliminating the energy cost of erasing information.
As Moore's Law approaches its physical limits, seeking breakthroughs from the physical nature of computation may be one of the important paths to sustaining growth in computing power.
Energy recovery circuits themselves introduce additional overhead in terms of complexity and chip area.
Reversible computing still has a considerable distance to go before large-scale commercialization, needing to overcome the industrial inertia of design toolchains, manufacturing processes, and ecosystems that the traditional semiconductor industry has built around irreversible logic.
