The entangled coherent states (ECSs) have been widely used to realize quantum
information processing tasks. However, the ECSs may suffer from photon loss and …

We study quantum phase sensing with asymmetric two-mode entangled coherent states
(ECSs) in which the two local amplitudes take different values. We find the asymmetry …

The advent of a new kind of entangled state known as hybrid entangled state, ie,
entanglement between different degrees of freedom, makes it possible to perform various …

In this work, we have applied the entanglement concentration protocols to partially
entangled subsets of classes of highly entangled multi-qubit states, created on IBM quantum …

We present an efficient hyperentanglement concentration protocol (hyper-ECP) for two-
photon six-qubit systems in nonlocal partially hyperentangled Bell states with unknown …

We proposed two entanglement concentration protocols (ECPs) to obtain maximally
entangled Greenberger-Horne-Zeilinger (GHZ)-type entangled coherent state (ECS) from …
