Exploring the topology of a non-Hermitian superconducting qubit using shortcuts to adiabaticity
Serra Erdamar, Maryam Abbasi, Weijian Chen +3
Open quantum systems described by a non-Hermitian Hamiltonian exhibit rich dynamics due to the topology of their complex energy spectrum. By encircling an exceptional point degener…
A geometrical description of non-Hermitian dynamics: speed limits in finite rank density operators
Niklas Hörnedal, Oskar A. Prośniak, Adolfo del Campo +1
Non-Hermitian dynamics in quantum systems preserves the rank of the state density operator. Using this insight, we develop a geometric framework to describe its time evolution. In…
Geometric Operator Quantum Speed Limit, Wegner Hamiltonian Flow and Operator Growth
Niklas Hörnedal, Nicoletta Carabba, Kazutaka Takahashi +1
Quantum speed limits (QSLs) provide lower bounds on the minimum time required for a process to unfold by using a distance between quantum states and identifying the speed of evolut…
