To study quantum remote control in the form of hierarchical quantum sharing, by using a
Hadamard gate, control-NOT gates and rotation gates, we construct a five-qubit partially …

This paper investigates the impact of dipole interactions and the initial quantum state
configurations within a quantum system on teleported quantum correlations involving a pair …

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 …

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 …

We first give one deterministic universal scheme of an arbitrary multi-qubit state with three
authorized agents via four-qubit cluster states. Then the scheme is extended to multiple …

In this work, we have studied a theoretical quantum controlled teleportation scheme for n-
qubit quantum state. We know very well that the preparation and maintenance of multi qubit …

The proposed controlled quantum teleportation schemes must prepare the entangled state
in advance, hence a novel controlled quantum teleportation scheme based on quantum …

The proposed hierarchical quantum operation sharing scheme cannot solve the supervision
problem of the highest power owner. Therefore, with the help of the local operations and …

We present a theoretical scheme for quantum controlled teleportation, which transmits a Bell
state from sender Alice to remote receiver Bob via a seven-qubit entangled state under the …

In this paper, a novel protocol of bidirectional controlled quantum teleportation (BCQT) via
seven-qubit state is proposed. Where Alice and Bob, two legitimate users, can teleport two …
