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…
Higher-order exceptional points in composite non-Hermitian systems
Jan Wiersig, Weijian Chen
We show that a composite quantum system described by the tensor product of multiple systems each with a leading-order exceptional point (a non-Hermitian degeneracy at which not onl…
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…
Chiral Bell-state transfer via dissipative Liouvillian dynamics
Shishir Khandelwal, Weijian Chen, Kater W. Murch +1
Chiral state transfer along closed loops in the vicinity of an exceptional point is one of the many counter-intuitive observations in non-Hermitian physics. The application of this…
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…
