Alexander Barg

I am a Professor in the Department of ECE and Institute of Systems Research of the University of Maryland, with affiliate appointments in the Departments of Computer Science and Mathematics. I am also an affiliate fellow of the UMD/NIST Joint Center for Quantum Information and Computer Science (QuICS).

Current research:

Quantum codes, in particular, qubit codes and their transversal logical gates; permutation invariant codes for correcting deletions and amplitude damping noise; bosonic Fock state codes; approximate quantum error correction.

Data representation on graphs (finite and infinite) wherein the contents of a vertex is determined by the values of its neighbors in the graph. For infinite graphs, for instance, grids, this group of problems has connections with methods of dynamical systems and equilibrium statistical mechanics (capacity and entropy maximizing measures; phase transitions and uniqueness of Gibbs distributions)

See Publications as well as my GoogleScholar profile for more details about my research .

Teaching: I occasionally teach a special topics course on "Modern discrete probability". Recently I also taught another topics course on "Classical and Quantum Codes" (co-taught with Victor Albert), both cross-listed between ECE, CS, and Math. I regularly teach graduate courses in Random Processes, Information Theory, and well as undergraduate classes.
