On adiabatic evolution for a general time-dependent quantum system
Kyu Hwang Yeon, Jeong Ryeol Choi, Shou Zhang +1
The unitary operator corresponding to the classical canonical transformation that connects a general closed system to an open system under adiabatic conditions is found. The quantu…
Controlled Secure Direct Communication by Using GHZ Entangled State
Yan Xia, Chang-Bao Fu, Feng-Yue Li +3
We present a controlled secure direct communication protocol by using Greenberger-Horne-Zeilinger (GHZ) entangled state via swapping quantum entanglement and local unitary operatio…
Controlled Quantum Dense Coding in a Four-particle Non-maximally Entangled State via Local Measurements
Chang-Bao Fu, Yan Xia, Bo-Xue Liu +3
A controlled quantum dense coding scheme is investigated with a four-particle non-maximal quantum channel. The amount of classical information is shown to be capable of being contr…
Entangled States Generated via Two Superconducting Quantum Interference Devices(SQUIDs) in cavity QED
Yan Li, Shou Zhang, Kyu-Hwang Yeon +1
We propose a scheme for generating entangled states for two superconducting quantum interference devices in a thermal cavity with the assistance of a microwave pulse.
Quantum Dialogue by Using the GHZ State
Yan Xia, Chang-Bao Fu, Shou Zhang +3
We present a quantum dialogue protocol by using the Greenberger-Horne-Zeilinger (GHZ) state. In this paper, we point out that the `quantum dialogue' communication scheme recently i…
Three-party quantum secure direct communication based on Greenberger-Horne-Zeilinger states
Xing-Ri Jin, Xin Ji, Ying-Qiao Zhang +4
We present a three-party simultaneous quantum secure direct communication (QSDC) scheme by using Greenberger-Horne-Zeilinger (GHZ) states. This scheme can be directly generalized t…
