Introduction
Moletronics II
To effectively address this question, the JASONs needed to evaluate the current state-of-the-art in
molecular-scale electronic devices. The current perfOlmance characteristics will set some
boundaries on the types of device functions that have been accomplished and additionally will
frame the types of devices that can be envisioned, how such devices might be addressed, and what
types of architectures might be used. This JASON study therefore attempted to address key
milestones and outstanding research issues on the single molecular electronic device scale which
must be defined before appropriate questions concerning the interconnect/architecture scale can
even be formulated. The goal was to identify bottlenecks that will be faced when attempting to
transition current research on single molecular-scale electronic devices into macroscopically
addressable, potentially useful, computational schemes and systems.

Molecular electronics has been popularly represented as a one-to-one replacement for Si-based
microelectronics. Before proceeding to our technical discussion of this possibility, we first note that
alternative perspectives are likely to be valuable.
Technical Issues for Molecule-Based Computation
Molecular- based computation must compete with Si-based computation. Before embarking on a
detailed technical evaluation of where technical advantage may lie, it is useful to frame the key
technical issues that will be involved with implementation of a molecular electronic computa-tional
system. These issues can be usefully framed in terms of a point/counterpoint set of statements.
Such statements can be divided into two categories: those that are optimistic (0) about the future of
molecular electronic devices, and conversely those that are pessimistic (p) about the prospects for
constructing a useful molecular-scale computational computing system. These issues form a good
basis for discussion of the various technical aspects of concern that form the remainder of the
report.
Summary
• Quantum Computing
- Completely different computational worldview
- Technically difficult physical implementation
- Basic experimental research underway to demonstrate
simple logic operations
- Implementation issues for error correction will be much more
serious than 1/0
