Non-markovianity and bound states in quantum walks with a phase impurity
B. Danacı, G. Karpat, İ. Yalçınkaya +1
We study a quantum walker on a one-dimensional lattice with a single defect site characterized by a phase. The spread and localization of discrete-time quantum walks starting at th…

Invariant entanglement and generation of quantum correlations under global dephasing
G. Karpat
We investigate the dynamics of quantum entanglement and more general quantum correlations quantified respectively via negativity and local quantum uncertainty for two qubit systems…

Continuous dynamical decoupling and decoherence-free subspaces for qubits with tunable interaction
İ. Yalçınkaya, B. Çakmak, G. Karpat +1
Protecting quantum states from the decohering effects of the environment is of great importance for the development of quantum computation devices and quantum simulators. Here, we…
