- Universal Dynamic Decoupling and Quantum Walks in Functional Spaces
- Time: 10:00 am
- Place: 5310 Chamberlin
- Speaker: Adilet Imambekov, Rice University
- Abstract: We study the universal dynamic decoupling (DD) schemes, which can restore the coherence of quantum systems (such as qubits) independent of the details of system-environment interaction. We introduce a general mapping between DD sequences and quantum walks in functional 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 same framework.
