Today, the field has a substantial body of academic literature. A wide variety of reversible device concepts, [[logic gate]]s, [[electronic circuit]]s, processor architectures, [[programming language]]s, and application [[algorithm]]s have been designed and analyzed by [[physicist]]s, [[electrical engineer]]s, and [[computer scientist]]s.

This field of research awaits the detailed development of a high-quality, cost-effective, nearly reversible logic device technology, one that includes highly energy-efficient [[clocking]] and [[synchronization]] mechanisms, or avoids the need for these through asynchronous design. This sort of solid engineering progress will be needed before the large body of theoretical research on reversible computing can find practical application in enabling real computer technology to circumvent the various near-term barriers to its energy efficiency, including the von Neumann–Landauer bound. This may only be circumvented by the use of logically reversible computing, due to the [[Second Law of Thermodynamics|second law of thermodynamics]].<ref>{{Cite book |last=Frank |first=Michael P. |title=Reversible Computation |chapter=Physical Foundations of Landauer's Principle |date=2018 |editor-last=Kari |editor-first=Jarkko |editor2-last=Ulidowski |editor2-first=Irek |chapter-url=https://link.springer.com/chapter/10.1007/978-3-319-99498-7_1 |series=Lecture Notes in Computer Science |volume=11106 |language=en |___location=Cham |publisher=Springer International Publishing |pages=3–33 |arxiv=1901.10327 |doi=10.1007/978-3-319-99498-7_1 |isbn=978-3-319-99498-7|s2cid=52135244 }}</ref>
