Dynamical self-dual criticality in Fibonacci-monitored quantum Ising chains
Finn Eckstein, Harald Schmid, Quinten Preiss +3
For the quantum phase transition in the transverse-field Ising chain, Kramers-Wannier duality not only protects its critical properties but also pinpoints the location of the phase…

Learning transitions of topological surface codes
Finn Eckstein, Bo Han, Simon Trebst +1
For the surface code, topological quantum order allows one to encode logical quantum information in a robust, long-range entangled many-body quantum state. However, if an observer…

Robust teleportation of a surface code and cascade of topological quantum phase transitions
Finn Eckstein, Bo Han, Simon Trebst +1
Teleportation is a facet where quantum measurements can act as a powerful resource in quantum physics, as local measurements allow to steer quantum information in a non-local way.…
