Our results suggest that the indefinite causal order along with a tiny amount of quantum discord can act as a resource in creating nonzero quantum coherence in the absence of entanglement. This finding may have some interesting applications on its own where discord can be consumed as a resource. We find that when the indefinite causal order of channels acts on one half of the entangled pair, then the shared state loses entanglement, but can retain nonzero quantum discord. We show this specifically for the superposition of two completely depolarizing channels, two partially depolarizing channels and one completely depolarizing channel along with a unitary operator. Here, we present a method for the creation of quantum coherence at a remote location via the use of entangled state and indefinite causal order. However, if there is a noisy channel acting on one side of the shared resource, then it is not possible to create perfect quantum coherence remotely. Quantum coherence of an arbitrary qubit can be created at a remote location using maximally entangled state, local operation and classical communication. Recently.Quantum coherence is a prime resource in quantum computing and quantum communication. Theory of quantum coherence as a physical resource has only been initiated Despite theįundamental importance of quantum coherence, the development of a rigorous Years, research on the presence and functional role of quantum coherence inīiological systems has also attracted a considerable interest.
