Dzyaloshinskii-Moriya interaction as a fast quantum information scrambler
Fatih Ozaydin, Azmi Ali Altintas, Can Yesilyurt +1
Black holes are conjectured to be the fastest information scramblers, and within holographic duality, the speed of quantum information scrambling of thermal states of quantum syste…
Nonlocal Activation of Bound Entanglement via Local Quantum Zeno Dynamics
Fatih Ozaydin, Cihan Bayindir, Azmi Ali Altintas
Bound entanglement was shown to be activated [P. Horodecki \textit{et al.,} Phys. Rev. Lett. \textbf{82,} 1056 (1999)] in the sense that the entanglement of a spatially separated t…
Deterministic preparation of W states via spin-photon interactions
Fatih Ozaydin, Can Yesilyurt, Sinan Bugu +1
Spin systems such as silicon or nitrogen vacancy centers in diamond, quantum dots and quantum dot molecules coupled to optical cavities appear as key elements for creating quantum…
Deterministic generation of a four-qubit W state using one- and two-qubit gates
Firat Diker, Can Yesilyurt
We propose an optical scheme to build an entangled network composed of W state based on polarization encoded qubits (photons). This new setup consists of 2 cNOT gates, 4 V gates, 2…
Deterministic Local Expansion of W States
Can Yesilyurt, Sinan Bugu, Fatih Ozaydin +4
In large quantum systems multipartite entanglement can be found in many inequivalent classes under local operations and classical communication. Preparing states of arbitrary size…
Constructing Quantum Logic Gates Using q-Deformed Harmonic Oscillator Algebras
Azmi Ali Altintas, Fatih Ozaydin, Can Yesilyurt +2
We study two-level q-deformed angular momentum states and us- ing q-deformed harmonic oscillators, we provide a framework for con- structing qubits and quantum gates. We also prese…
Fusing multiple W states simultaneously with a Fredkin gate
Fatih Ozaydin, Sinan Bugu, Can Yesilyurt +3
We propose an optical scheme to prepare large-scale entangled networks of W states. The scheme works by simultaneously fusing three polarization-encoded W states of arbitrary size…
Enhancing the W State Quantum Network Fusion Process with A Single Fredkin Gate
Sinan Bugu, Can Yesilyurt, Fatih Ozaydin
Integrating a single Fredkin (controlled swap) gate to the previously introduced W state fusion mechanism (Ozdemir et al, N. J. Phys. 13, 103003, 2011) and using an ancillary photo…
