“…A similar topics also were discussed [32,33]. In addition, the close relationship between quantum multipartite masker and quantum teleportation was studied and a new masking scheme [34]. These conclusions all convey a signal that quantum information masking has wide prospect in the security of quantum information process.…”

Quantum information masking is a protocol that hides the original quantum information from subsystems and spreads it over quantum correlation, which is available to multipartite except bipartite systems. In this work, we explicitly study the quantum information masking in multipartite scenario and prove that there exists an universal quantum masker can mask the information encoding in the unknown states into a multipartite system with lower-dimensional local systems, namely, all the k-level quantum states can be masked into a m-qudit systems (m ‒ 4) whose local dimension d k . In order to observe the masking process intuitively, explicitly controlled operations are provided. Our scheme well demonstrates the abundance of quantum correlation between multipartite quantum system and has potential application in the security of quantum information processing.

“…It would also be interesting to consider an unified view of the imperfect cloning of steering, teleportation and multipartite maskers, as these protocols have similar formalisms. The relationship between the latter two has actually been established very recently [36]. In particular, we hope that the imperfect cloning of steering can be implemented in laboratories with the recent techniques developed in teleportation [37,38] and quantum masking [39,40].…”

The property of steering in a global state allows an observer to affect the postmeasured states of a subsystem by performing different local measurements on the other part. We show that, in general, this property cannot be perfectly cloned by any joint operation between a steered subsystem and a third system. The perfect cloning is viable if and only if the initial state is of zero-discord. We also investigate the process of cloning the steered qubit of a Bell state by using a universal cloning machine. The quantum steering, as a type of quantum correlation existing in the states without a local-hidden-state model, can be found in both of the copy subsystems. This breaks the recent conclusion of no-cloning of quantum steering in [npj Quantum Inf. 2, 16020 (2016)] based on a mutual information criterion for quantum steering.

Quantum steering in a global state allows an observer to remotely steer a subsystem into different ensembles by performing different local measurements on the other part. We show that, in general, this property cannot be perfectly cloned by any joint operation between a steered subsystem and a third system. The perfect cloning is viable if and only if the initial state is of zero-discord. We also investigate the process of cloning the steered qubit of a Bell state by using a universal cloning machine. Einstein-Podolsky-Rosen (EPR) steering, which is a type of quantum correlation existing in the states without a local-hidden-state model, can be found in both of the copy subsystems. This breaks the recent conclusion of no-cloning of quantum steering (EPR steering) in [npj Quantum Inf. 2, 16020 (2016)] based on a mutual information criterion for EPR steering.
