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…
Speeding up entanglement generation by proximity to higher-order exceptional points
Zeng-Zhao Li, Weijian Chen, Maryam Abbasi +2
Entanglement is a key resource for quantum information technologies ranging from quantum sensing to quantum computing. Conventionally, the entanglement between two coupled qubits i…
Decoherence Induced Exceptional Points in a Dissipative Superconducting Qubit
Weijian Chen, Maryam Abbasi, Byung Ha +3
Open quantum systems interacting with an environment exhibit dynamics described by the combination of dissipation and coherent Hamiltonian evolution. Taken together, these effects…
Topological quantum state control through exceptional-point proximity
Maryam Abbasi, Weijian Chen, Mahdi Naghiloo +2
We study the quantum evolution of a non-Hermitian qubit realized as a submanifold of a dissipative superconducting transmon circuit. Real-time tuning of the system parameters to en…
Quantum jumps in the non-Hermitian dynamics of a superconducting qubit
Weijian Chen, Maryam Abbasi, Yogesh N. Joglekar +1
We study the dynamics of a driven non-Hermitian superconducting qubit which is perturbed by quantum jumps between energy levels, a purely quantum effect with no classical correspon…
Quantum state tomography across the exceptional point in a single dissipative qubit
M. Naghiloo, M. Abbasi, Yogesh N. Joglekar +1
Open systems with gain and loss, described by non-trace-preserving, non-Hermitian Hamiltonians, have been a subject of intense research recently. The effect of exceptional-point de…
