Quantum fisher information of several qubitsin the superposition of A GHZ and two W stateswith arbitrary relative phase
Özaydın, Fatih; Altıntaş, Azmi Ali; Buğu, Sinan; Yeşilyurt, Can; Arık, Metin (Springer/Plenum Publishers, 2014-09)We study the quantum Fisher information (QFI) of a system of several particles which is in a superposition of a GHZ and two W states with arbitrary relative phase. We show that as the number of particles increases from 3 ... -
Quantum metrology: Surpassing the shot-noise limit with Dzyaloshinskii-Moriya interaction
Özaydın, Fatih; Altıntaş, Azmi Ali (Nature Publishing Group, 2015-11-09)Entanglement is at the heart of quantum technologies such as quantum information and quantum metrology. Providing larger quantum Fisher information (QFI), entangled systems can be better resources than separable systems ... -
Surpassing the classical limit in magic square game with distant quantum dots coupled to optical cavities
Buğu, Sinan; Özaydın, Fatih; Kodera, Tetsuo (Nature Research, 2020-12-17)The emergence of quantum technologies is heating up the debate on quantum supremacy, usually focusing on the feasibility of looking good on paper algorithms in realistic settings, due to the vulnerability of quantum systems ... -
Temperature control in dissipative cavities by entangled dimers
Dağ, Ceren B.; Niedenzu, Wolfgang; Özaydın, Fatih; Müstecaplıoğlu, Özgür Esat; Kurizki, Gershon (Amer Chemical Soc, 2019-02-21)We show that the temperature of a cavity field can be drastically varied by its interaction with suitably entangled atom pairs (dimers) traversing the cavity under realistic atomic decoherence. To this end we resort to the ... -
Work and heat value of bound entanglement
Tuncer, Aslı; Izadyari, Mohsen; Müstecaplıoğlu, Özgür Esat; Özaydın, Fatih; Daǧ, Ceren B. (Springer, 2019-12)Entanglement has recently been recognized as an energy resource which can outperform classical resources if decoherence is relatively low. Multi-atom entangled states can mutate irreversibly to so-called bound entangled ...
