Nonlinear quantum evolution of a dissipative superconducting qubit
Orion Lee, Qian Cao, Yogesh N. Joglekar +1
Unitary and dissipative models of quantum dynamics are linear maps on the space of states or density matrices. This linearity encodes the superposition principle, a key feature of…

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…
