Long-lifetime quantum storages accessible to the telecom photonic infrastructure are
essential to long-distance quantum communication. Atomic quantum storages have …

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 …

Spin systems such as silicon and nitrogen-vacancy centers in diamond, quantum dots, and
quantum dot molecules coupled to optical cavities appear to be key elements for creating …

We study the quantum Fisher information (QFI) of W states in the basic decoherence
channels. We show that, as decoherence starts and increases, under i) depolarizing, QFI …

We propose a deterministic scheme of generating genuine multiparty entangled states in
quantum networks of arbitrary size having various geometric structures—we refer to it as …

W state is a key resource in quantum communication. Fusion technology has been proven to
be a good candidate for preparing a large-size W state from two or more small-size W states …

Entanglement among multiple particles is a keystone for not only fundamental research on
quantum information but also various practical quantum information applications. In …

In quantum information, W states are a central class of multipartite entangled states because
of their robustness against noise and their use in many quantum processes. Their …

We present a deterministic scheme for generating large-scale atomic W states in a cavity
QED system via a simple expansion mechanism, which is realized only by a detuned …

In large quantum systems, multipartite entanglement can be found in many inequivalent
classes. Preparing states of arbitrary size in different classes is important for performing a …
