This article presents a new scheme for asymmetric bidirectional controlled quantum
teleportation (ABCQT) protocol of two-and three-qubit unknown states. In the protocol, Alice …

Cyclic quantum teleportation schemes requires at least the existence of three collaborators
acting all as senders and receivers of quantum information, each one of them has an …

This article presents a new bidirectional teleportation protocol for an arbitrary number of
qubits which employs 2 n entangled Bell-states (4n-qubits) as the quantum channel. Alice …

Quantum teleportation is a technique for allowing one party to transfer an unknown state to
the other party some distance away. Different types of teleportation, including bidirectional …

This paper proposes an asymmetric tridirectional quantum teleportation (TQT) protocol that
uses a seven-qubit cluster states as the quantum channels of each party. In this scheme, any …

This paper presents a new bidirectional quantum teleportation (BQT) protocol in which users
can simultaneously transmit an arbitrary number of particles to each other via a four-qubit …

This article introduces two controlled quantum broadcast protocols which they utilize 6-qubit
and 6 n-qubit (generalized scheme) cluster states as the quantum channel, respectively. The …

Based on a seven-qubit entangled state, Chen et al (2020 Int. J. Theor. Phys. 59 1402)
presented a scheme for controlled quantum teleportation. Using the same quantum channel …

In this paper, we present a scheme of bidirectional quantum controlled teleportation of three-
qubit state by using GHZ states. Alice transmits an unknown three-qubit entangled state to …

In this paper, a theoretical scheme for bidirectional quantum teleportation by using a four-
qubit GHZ state and two Bell states as a quantum channel is proposed. In this scheme, two …
