Three schemes of remote information concentration based on ancilla-free phase-covariant telecloning

Three schemes of remote information concentration based on ancilla-free phase-covariant telecloning In this paper, remote information concentration is investigated which is the reverse process of the $$1\rightarrow 3$$ 1 → 3 optimal asymmetric economical phase-covariant telecloning (OAEPCT). The OAEPCT is different from the reverse process of optimal universal telecloning. It is shown that the quantum information via $$1\rightarrow 3$$ 1 → 3 OAEPCT procedure can be remotely concentrated back to a single qubit with a certain probability via several quantum channels. In these schemes, we adopt Bell measurement to measure the joint systems and use projected measurement and positive operator-valued measure to recover the original quantum state.

Abstract

In this paper, remote information concentration is investigated which is the reverse process of the $$1\rightarrow 3$$ 1 → 3 optimal asymmetric economical phase-covariant telecloning (OAEPCT). The OAEPCT is different from the reverse process of optimal universal telecloning. It is shown that the quantum information via $$1\rightarrow 3$$ 1 → 3 OAEPCT procedure can be remotely concentrated back to a single qubit with a certain probability via several quantum channels. In these schemes, we adopt Bell measurement to measure the joint systems and use projected measurement and positive operator-valued measure to recover the original quantum state. The results shows non-maximally entangled quantum resource can be applied to information concentration.
