We describe two different proposals for implementing mathematically re
versible and dissipationless logic in nanoelectronic systems. Both are
amenable to quantum computation and use interacting single electrons
housed in quantum dots to elicit logic functions. In these systems, qu
bit errors accruing from decoherence events can be partially remedied
by quantum error control coding. We present some new results on burst-
correcting quantum codes that can address correlated errors in nanostr
uctures. (C) 1998 Academic Press Limited.
