Controlled Quantum Teleportation Through Noisy GHZ Channel

Abstract

In this paper, we propose two physical schemes for teleporting an unknown atomic state through noisy channel in cavity QED. The quantum channel is a noisy one — a mixed GHZ state, which is more realistic in quantum information processing. We solve analytically a master equation in the Lindblad form with (L2,z, L3,z, L4,z)-type of noise in cavity QED. A comparison between the two protocols are discussed.

In this paper, we propose two physical schemes for teleporting an unknown atomic state through noisy channel in cavity QED. The quantum channel is a noisy one—a mixed GHZ state, which is more realistic in quantum information processing. We solve analytically a master equation in the Lindblad form with (L_(2,z), L_(3,z), L_(4,z))-type of noise in cavity QED. A comparison between the two protocols are discussed.

Teleportation of Unknown Atomic Entangled States Using GHZ Class States

Zhao Yan

We propose two physical schemes, which can teleport unknown atomic entangled states from user A (Alice) to user B (Bob) via GHZ class states as quantum channel. The two schemes are both based on cavity QED techniques. In the two schemes, teleportation and distillation procedures can be realized simultaneously. The second teleportation scheme is more advantageous than the first one.

Controlled Teleportation of an Arbitrary Two-Atom State in Cavity QED

Shou Zhang

We propose a scheme for controlled teleportion of an arbitrary two-atom state in cavity QED. In the scheme a GHZ state and an EPR pair are chosen as quantum channels. The sender can teleport quantum information to the receiver with the help of the controller. In the teleportation process two pairs of atoms interact respectively with two identical single-mode cavities; meanwhile, the two pairs of atoms are respectively driven by two identical classical fields. The scheme is insensitive to the cavity decay and thermal field and the success probability is 1.0.

Scheme for Teleportation of Unknown Entangled Atomic States via Cavity Decay

Zhang Li-hua, Zheng‐Yuan Xue, Yang Ming +1 more

We present a physical scheme to teleport an unknown atomic entangled state via cavity decay. In the teleportation process, four-particle Greenberger–Horne–Zeilinger (GHZ) state is used as quantum channel, and two unknown entangled atoms and two of four atoms in the four-particle GHZ state are trapped in four leaky cavities, respectively. Based on the joint detection of the photons leak out from the four cavities, we can teleport an unknown entangled state to two other remote atoms with certain probability and high fidelity.
