Sending or blocking current through a device with
three quantum dots depends on their geometrical
configuration and connections to leads.
When 3 dots are aligned, with two connected to
external leads (L and R)
current flows if the dots are in resonance.
Attaching a third lead (P) introduces decoherence
and reduces the current.
These results may have applications in the design
of entangled quantum bits useful for quantum
encryption codes.

Education Projects included in this grant are
within the research areas of several doctoral
students from Brazil (Ginetom Diniz), Florida
(Brian Lane), and Ohio (Ahn Ngo and Gregory
Petersen)
Postdoctoral fellows Mehdi Zarea, Edson Vernek
and Carlos Büsser are actively working on
different topics that have resulted in
publications. They also presented their results
in various national and international
conferences.
Carlos Büsser (Brazil/US) held the position of
traveling postdoctoral fellow commuting between
Oakland Univ. and OU.
