Quantum Optimal Control of a Lambda System in the Density Matrix Formulation
Julia Cen, Domenico D'Alessandro
In various physical implementations of quantum information processing, qubits are realized in a Lambda type system configuration as two stable lower energy levels coupled indirectl…
Quantum dynamics of non-Hermitian many-body Landau-Zener systems
Rajesh K. Malla, Julia Cen, Wilton J. M. Kort-Kamp +1
We develop a framework to solve a large class of linearly driven non-Hermitian quantum systems. Such a class of models in the Hermitian scenario is commonly known as multi-state La…
Anti--symmetric Qubit: Decoherence and Entanglement Entropy
Julia Cen, Avadh Saxena
We investigate a two-level spin system based anti-parity-time (anti-)-symmetric qubit and study its decoherence as well as entanglement entropy properties. We compare…
Time-dependent Darboux (supersymmetric) transformations for non-Hermitian quantum systems
Julia Cen, Andreas Fring, Thomas Frith
We propose time-dependent Darboux (supersymmetric) transformations that provide a scheme for the calculation of explicitly time-dependent solvable non-Hermitian partner Hamiltonian…
