Splitting an Arbitrary Two-Qubit State via a Genuine Six-Qubit Entangled State

Abstract

We propose a realizable quantum information splitting scheme for an arbitrary two-qubit state. In our scheme, a genuine six-qubit entangled state is used as quantum channel. The sender and controller only need to perform Bell-state measurements and single-qubit measurements, respectively. The receiver can reconstruct the arbitrary two-qubit state by classical communication and local operations.
