摘要:
Employing quantum registers, we first proposed a novel (2, 3) quantum threshold scheme based on Einstein-Podolsky-Rosen (EPR) correlations in this letter. Motivated by the present threshold scheme, we also propose a controlled communication scheme to transmit the secret message with a controller. In the communication protocol, the encoded quantum message carried by particles sequence, is transmitted by legitimate communicators.
