SUMMARY:Universal Dynamic Decoupling and Quantum Walks in Functional S
 paces\, R. G. Herb Condensed Matter Seminar\, Adilet Imambekov\, Rice 
 University
DESCRIPTION:We study the universal dynamic decoupling (DD) schemes\, w
 hich can restore the coherence of quantum systems (such as qubits) ind
 ependent of the details of system-environment interaction. We introduc
 e a general mapping between DD sequences and quantum walks in function
 al spaces\, and use it to prove the universality of various DD schemes
  such as quadratic DD\, nested Uhrig DD\, and Uhrig concatenated DD.  
 The validity of previously known universal schemes of concatenated DD\
 , Uhrig DD and concatenated Uhrig DD is also established using the sam
 e framework.
