We propose an optical scheme to prepare large-scale entangled networks of $W$ states. The works by simultaneously fusing three polarization-encoded states arbitrary size via accessing only one qubit each state. It is composed a Fredkin gate (controlled-swap gate), two fusion gates [as proposed in S. K. Ozdemir et al., New J. Phys. 13, 103003 (2011)], and $H$-polarized ancilla photon. Starting with $n$-qubit states, the prepares new state $3(n\ensuremath{-}1)$ qubits after postselection if...
Entanglement has been studied extensively for unveiling the mysteries of non-classical correlations between quantum systems. In bipartite case, there are well known measures quantifying entanglement such as concurrence, relative entropy (REE) and negativity, which cannot be increased via local operations. It was found that sets non-maximally entangled states two qubits, comparing these may lead to different orderings states. On other hand, although it is not an measure monotonic under...
Abstract Entanglement is at the heart of quantum technologies such as information and metrology. Providing larger Fisher (QFI), entangled systems can be better resources than separable in However effects on entanglement dynamics decoherence usually decrease QFI considerably. On other hand, Dzyaloshinskii-Moriya (DM) interaction has been shown to excite entanglement. Since an increase does not imply also there are cases where decreases increases, it interesting study influence DM In this...
In large quantum systems multipartite entanglement can be found in many inequivalent classes under local operations and classical communication. Preparing states of arbitrary size different is important for performing a wide range protocols. W states, particular, constitute class with variety networking However, all known schemes preparing are probabilistic, resource requirements increasing at least sub-exponentially. We propose deterministic scheme that requires no prior performed locally....
Although tsunamis occur less frequently compared to some other natural disasters, they can be extremely devastating in the nearshore environment if occur. An earthquake of magnitude 6.9 Mw occurred on 30 October 2020 at 12:51 p.m. UTC (2:51 GMT+03:00) and its epicenter was approximately 23 km south İzmir province Turkey, off Greek island Samos. The tsunami event triggered by this is known as İzmir-Samos (Aegean) tsunami, paper, we study hydrodynamics using these artificial intelligence (AI)...
Decoherence is a major issue in quantum information processing, degrading the performance of tasks or even precluding them. Quantum error-correcting codes, creating decoherence-free subspaces, and Zeno effect are among means for protecting systems from decoherence. Increasing number qubits system to be utilized task as resource expands state space. This creates opportunity engineer way that improves protect against Here, we consider thermalization machine four-qubit atomic states its...
We study the quantum Fisher information (QFI) of W states and -like under decoherence.In particular, we nd that on contrary to amplitude damping depolarizing decoherence, a state 3 qubits obtained by discarding 1 qubit genuine 4 is more robust than amplifying phase decoherence.
Quantum Fisher information has recently been an essential tool for analyzing the phase sensitivity of quantum states in various tasks, requiring high precision, such as clock synchronization, positioning and many applications which include interferometers.Due to interactions with environment, all systems are subject decoherence eects.Therefore research on under attracting more attention.In this work, information, we study bipartite correlations, particular four Bell pairs amplitude damping...
Quantum entanglement is one of key concepts in quantum communication engineering. Ordering the systems according to their measures a popular problem field. For two level (qubit) particles, state ordering has been studied with respect well-known such as Concurrence, Negativity and Relative Entropy Entanglement (REE) [1-5]. In this work, we study two-qubit Fisher Information vs. Concurrence. particular, constructing 1K random states calculating Concurrences Negativities, obtain orderings by...

Bound entanglement was shown to be activated [P. Horodecki et al., Phys. Rev. Lett. 82, 1056 (1999)] in the sense that of a spatially separated two-qutrit system can increased with nonzero probability via sufficiently large number preshared bound-entangled states, local three-level controlled operations, and classical communications. Here we present quantum Zeno scheme for activating bound which is based only on single-particle rotations threshold measurements. In our scheme, neither states...
An arbitrary amount of entanglement shared among nodes a quantum network might be nondistillable if the lack information on entangled Bell pairs they share. Making such system distillable, which is called superactivation bound (BE), was shown to possible through systematic teleportation between nodes, requiring implementation controlled-gates scaling with number nodes. In this work, we show in two scenarios that BE implement proposed local Zeno strategies based only single qubit rotations...
Detectors based on the bulk-Micromegas technology exhibit position resolution better than 100 μm at counting rates of up to several tens kHz/cm2, along with trigger capabilities. These characteristics, combined detector's mechanical robustness and possibility for cost-effective industrial production, makes them a promising candidate ATLAS Muon Spectrometer upgrade in future luminosity enhancement LHC. The R&D project status will be presented together obtained results effort define baseline...
In this work, we study the quantum Fisher information (QFI) per particle of an open (particles can enter and leave system) dissipative (far from thermodynamical equilibrium) steady state system two qubits in noisy channels. We concentrate on channels these are dephasing non-dephasing will show that under certain conditions QFI is slightly greater than 1 for both systems. This means systems be entangled.
