Topic: Concept, status and challenges of quantum structural engineering
Speaker: Alexandre Zagoskin, Loughborough University, UK
Abstract:
Current experimental techniques allow to fabricate, manipulate and maintain at least partial quantum coherence in structures comprising thousands of quantum bits. A direct simulation of quantum systems of this size using available classical computers is impossible, and the fundamental impossibility of the simulation of large quantum systems by classical means does not leave any hope for the brute force methods. It is therefore necessary to look for different approaches toward structural quantum engineering (i.e., design, characterization and optimization of large quantum coherent structures based on the properties of their constituent elements and their interconnections). A possible way forward opens if there exist qualitatively different regimes of operation of large quantum coherent structures controlled by universal, experimentally accessible dimensionless parameters. Some candidates for such parameters will be discussed.
