Techniques for Finding Exact Solutions of Interacting Dissipative Quantum Systems

Watch a technical seminar exploring analytical methods for solving complex dissipative quantum systems, presented by Alexander McDonald as part of the Qiskit Seminar Series. Learn how weak symmetries can be used to analytically diagonalize strongly-interacting dissipative Markovian Lindblad master equations relevant to modern quantum processors. Discover a novel approach that implements an exact mean-field-like decoupling, enabling full understanding of characteristic energies and decay rates. Explore how reformulated third quantization provides intuitive insights into open quantum systems and serves as a foundation for perturbative analyses of more complex systems with non-linearities included in unperturbed theory. Gain valuable knowledge from McDonald's expertise in superconducting circuit theory, quantum non-reciprocity, and quantum sensing, developed through his work at the Université de Sherbrooke and the University of Chicago.
