This loss is a fundamental aspect of how computers operate. For example, when a computer adds two numbers together, it returns a single number for the total: 2 + 2 = 4. There’s a loss of information as you go from two numbers to one. You could have added 2 and 2, or you could have combined 1 and 3. The missing information makes the calculation irreversible. Computers that process information this way — and almost all of them do — are always going to lose some information as heat, no matter what.

With the concern that “Moore’s Law is dead,” new interest has grown for unconventional forms of computing. This includes: quantum computing (for atomic simulations and specific NP approximation algorithms) analog computing (for fast-and-efficient-but-error-prone computation, such as neural net inference) reversible computing (for maximum energy efficiency) It is believed that the most efficient computing devices would use little or no entropy during reversible computations, and only consume
