Abstract

A recently proposed protocol for two parties to securely and simultaneously
exchange inequivalent quantum states under the same control of a third party [Int. J. Theor. Phys. (2020); https://doi.org/10.1007/s10773-020-04657-0] is revisited. It is shown in this paper that the required tasks are equally well accomplished with a nonlocal resource which is greatly economized by rationally exploiting local resources. Furthermore, the economized nonlocal resource with appropriate local operations on local resources also allows exchanging inequivalent states other than those previously considered.
