- Abstract: The advent of a new kind of entangled state known as hybrid entangled state,
i.e., entanglement between different degrees of freedom, makes it possible to
perform various quantum computational and communication tasks with lesser
amount of resources. Here, we aim to exploit the advantage of these entangled
states in communication over quantum networks. Unfortunately, the entanglement
shared over the network deteriorates due to its unavoidable interaction with
surroundings. Thus, an entanglement concentration protocol is proposed to
obtain a maximally entangled hybrid Omega-type state from the corresponding
non-maximally entangled states. The advantage of the proposed entanglement
concentration protocol is that it is feasible to implement this protocol with
linear optical components and present technology. The corresponding linear
optical quantum circuit is provided for experimental realizations, while the
success probability of the concentration protocol is also reported. Thereafter,
we propose an application of maximally entangled hybrid state in the
hierarchical quantum teleportation network by performing information splitting
using Omega-type state, which is also the first hierarchical quantum
communication scheme in the hybrid domain so far. The present hybrid entangled
state has advantage in circumventing Pauli operations on the coherent state by
polarization rotation of single qubit, which can be performed with lesser
errors.
