The phenomenon of quantum mechanical interference may be used to control the conductivity of ballistic molecular wires. Using a simple model we demonstrate plausible effects and discuss its potential uses for constructing coherence-based molecular electronics.

Novel categories of electronic devices and quantum materials are obtained by pipelining the unitary evolution electron states as described Schroedinger's equation with non-unitary processes that interrupt coherent propagation electrons. These reside in fascinating transition regime between mechanics classical physics. The designed such a nonreciprocal state is achieved means broken inversion sy...
