Place: Room 130, East Single-Storey Building（国科大中关村校区东平房130室）

Speaker: Dr. Guo-Yi Zhu (Koln University --> HKUST (Guangzhou))

Abstract:

Measurement is an essential ingredient for teleportation, which can be harnessed to prepare long-range entangled many-body states. In this talk, I will give an overview over the measurement-induced quantum phase transitions for these long-range entangled states, including the GHZ-like Nishimori’s cat, topological surface code, and if time allows, the Majorana spin liquid.

Bio:

Guo-Yi obtained his PhD degree from Tsinghua University, supervised by Prof. Guang-Ming Zhang. He works as a postdoctoral fellow at the Max-Planck-Institute for the Physics of Complex Systems in Germany from 2019-2021, and afterwards, he joined Prof. S. Trebst's group at the Institute for Theoretical Physics, University of Cologne. He will join the faculty of Hong Kong University of Science and Technology (Guangzhou) this summer. His current interests lie at the interface between condensed matter physics and quantum information and quantum computation, aiming at understanding, preparing and teleporting the long-range entanglement phases of matter.
