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…

Engineering nonequilibrium steady states through Floquet Liouvillians
Weijian Chen, Maryam Abbasi, Serra Erdamar +3
We experimentally study the transient dynamics of a dissipative superconducting qubit under periodic drive towards its nonequilibrium steady states. The corresponding stroboscopic…

Constraining work fluctuations of non-Hermitian dynamics across the exceptional point of a superconducting qubit
Serra Erdamar, Maryam Abbasi, Byung Ha +4
Thermodynamics constrains changes to the energy of a system, both deliberate and random, via its first and second laws. When the system is not in equilibrium, fluctuation theorems…
