Algorithmic quantum heat engines
Kose, Emre; Cakmak, Selcuk; Gencten, Azmi; Kominis, Iannis K.; Mustecaplioglu, Ozgur E. (Amer Physical Soc, 2019)We suggest alternative quantum Otto engines, using heat bath algorithmic cooling with a partner pairing algorithm instead of isochoric cooling and using quantum SWAP operations instead of quantum adiabatic processes. Liquid ... -
Construction of four-qubit quantum entanglement for SI (S=3/2, I=3/2) spin system
Gun, Ahmet; Cakmak, Selcuk; Gencten, Azmi (Springer, 2013)In quantum information processing, spin-3/2 electron or nuclear spin states are known as two-qubit states. For SI (S = 3/2, I = 3/2) spin system, there are 16 four-qubit states. In this study, first, four-qubit entangled ... -
Irreversibility in a unitary finite-rate protocol: the concept of internal friction
Cakmak, Selcuk; Altintas, Ferdi; Mustecaplioglu, Ozgur E. (Iop Publishing Ltd, 2016)The concept of internal friction, a fully quantum mechanical phenomena, is investigated in a simple, experimentally accessible quantum system in which a spin-1/2 is driven by a transverse magnetic field in a quantum adiabatic ... -
Irreversible work and internal friction in a quantum Otto cycle of a single arbitrary spin
Cakmak, Selcuk; Altintas, Ferdi; Gencten, Azmi; Mustecaplioglu, Ozgur E. (Springer, 2017)We propose an arbitrary driven spin as the working fluid of a quantum Otto cycle in the presence of internal friction. The role of total allocated time to the adiabatic branches of the cycle, generated by different control ... -
Lipkin-Meshkov-Glick model in a quantum Otto cycle
Cakmak, Selcuk; Altintas, Ferdi; Mustecaplioglu, Ozgur E. (Springer Heidelberg, 2016)The Lipkin-Meshkov-Glick model of two anisotropically interacting spins in a magnetic field is proposed as a working substance of a quantum Otto engine to explore and exploit the anisotropy effects for the optimization of ...
