Abstract

We investigate schemes to securely distribute and reconstruct single-qubit and two-qubit arbitrary quantum states between two parties via tripartite GHZ states in cavity QED without joint measurement. Our schemes offer a simple way of demonstrating quantum state sharing in cavity QED. We also consider the generalization of our schemes to distribute and reconstruct a quantum state among many parties.
