Spin quantum heat engines with shortcuts to adiabaticity
Barış Çakmak, Özgür E. Müstecaplıoğlu
We consider a finite-time quantum Otto cycle with single and two-spin- systems as its working medium. In order to mimic adiabatic dynamics at a finite-time, we employ a shortc…
Collectively enhanced thermalization via multiqubit collisions
Angsar Manatuly, Wolfgang Niedenzu, Ricardo Román-Ancheyta +3
We investigate the evolution of a target qubit caused by its multiple random collisions with -qubit clusters. Depending on the cluster state, the evolution of the target qubit m…
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…
Robust multipartite entanglement generation via a collision model
Barış Çakmak, Steve Campbell, Bassano Vacchini +2
We examine a simple scheme to generate genuine multipartite entangled states across disjoint qubit registers. We employ a shuttle qubit that is sequentially coupled, in an energy p…
