Geometry versus excitation sector in the decoherence of asymmetric -qubit states
Sougata Bhattacharyya, Sovik Roy, Fatih Ozaydin
We investigate how network geometry and excitation sector separately control pairwise entanglement decay in asymmetric multipartite states. To disentangle these effects, we int…
Super-Link Fragility in Asymmetric W-Class States under Quantum Noise
Sougata Bhattacharyya, Fatih Ozaydin, Sovik Roy
The asymmetric three-qubit W-class state defines an isosceles entanglement-network geometry, (a) two vertex-base (VB) links form stronger bipartite conne…
Deterministic generation of large scale atomic W states
Xue-Ping Zang, Ming Yang, Fatih Ozaydin +2
We present a deterministic scheme for generating large-scale atomic W states in cavity QED system via a simple expansion mechanism, which is realized only by a detuned interaction…
Generating multi-atom entangled W states via light-matter interface based fusion mechanism
Xue-Ping Zang, Ming Yang, Fatih Ozaydin +2
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…
Generating multi-photon W-like states for perfect quantum teleportation and superdense coding
Ke Li, Fan-Zhen Kong, Ming Yang +3
An interesting aspect of multipartite entanglement is that for perfect teleportation and superdense coding, not the maximally entangled W states but a special class of non-maximall…
