RESEARCH EXPERIENCES AND ACHIEVEMENTS
Postdoctoral Research Associate
6/2004 - present, Department of Physics, Carnegie Mellon University, Pittsburgh, PA
Pursuing theoretical research, with
Dr. Robert B. Griffiths
,
on quantum information processing, quantum optics, and foundation of quantum physics.
- Currently conducting research on LOCC quantum
states discrimination.
- Currently conducting research on optimal unambiguous dense coding with partially entangled
quantum state as resource.
Research Assistant, Adjunct Lecturer
9/1996 - 8/2003, Hunter College, The City University of New York (CUNY), NY
Pursuing theoretical research, with
Dr. Janos A. Bergou
and
Dr. Mark Hillery
, on quantum information processing, quantum optics, and algorithms of quantum computing and quantum cryptography.
- Conducted theoretical research
on non-unitary quantum transformations. Developed a theoretical scheme
to evaluate the maximum successful probability of a non-unitary
transformation, which transforms non-orthogonal quantum states into
orthogonal ones.
- Derived a method to calculate
the optimal probability of unambiguous discrimination of quantum
states. Found several analytical solutions of optimum discrimination
under different conditions of the quantum states.
- Developed a strategy to
systematically build up an optical network to implement the optimum
discrimination of quantum states. The optical network utilizes linear
optical devices. Offered an approach to calculate the property of each
optical device in order to design the optical network.
- Proposed a now topic on
quantum states discrimination that optimally distinguishes two sets of
quantum states. Presented a fully analytical solution of the problem.
- Conducted theoretical research
on comparison of quantum states. Determined optimum probability of
success to identify two quantum states belonging to two different
quantum systems.
- Taught physics laboratory for five years. Duties included lecturing, instructing and grading.
