Controlled remote implementation of operations for many systems

HIGHLIGHTS

• What: The authors propose two quantum communication protocols namely dense coding and stealth coding. The authors develop the above protocols by constructing a multi-party quantum security protocol in terms of the so-called remote-controlled implementation of operations. The aim in this section is to send the unitary operation 𝑈=⊗𝑁 𝑗=1 exp to other 𝑗 participants assisted by the controller. To accomplish the goal , the authors implement the unitary operation 𝑈𝐶 to Charlie =ex on system belonging 𝑈𝑐,𝐶=|0⟩𝑐 ⟨0| ⊗ 𝐼𝐶 + |1⟩|𝑐 ⟨1| ⊗ 𝜎𝑛𝐶.
• Who: Chengxu Liu from the Capital Normal University High School, Beijing, China, have published the Article . . .
