But quantum mechanics is full of surprises. In 1958, Anderson discovered a mechanism by which disorder can stop equilibration. This phenomenon was later developed into the concept of many-body localization, which has been applied to a wide range of cases, from Hamiltonian dynamics to time-periodic quantum circuits. I will describe how we observed many-body localization in quantum circuits running on IBM quantum hardware, leading to one of the largest recent physics experiments on superconducting quantum hardware. I will show how static disorder can prevent quantum chaos and equilibration, and how this phenomenon arises from the presence of many hidden local integrals of motion, which we faithfully reconstruct. Bio: Oles Shtanko is a theoretical physicist and quantum computing researcher at IBM Quantum. After receiving his Ph.D. in physics from the Massachusetts Institute of Technology in 2019, he completed a postdoctoral fellowship at the University of Maryland College Park as part of the Joint Quantum Institute (JQI) and the Joint Center for Quantum Information and Computer Science (QuICS). Oles joined IBM in 2021, where he focuses on the intersection of condensed matter physics and quantum computing, open quantum systems, and quantum algorithms for current quantum hardware.
