Nanoelectronic implementations of reversible and quantum logic

We describe two different proposals for implementing mathematically reversible 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, qubit 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 nanostructures. (C) 1998 Academic Press Limited.
