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…
