A controlled teleportation scheme is presented. In this scheme, quantum information of a
single-qubit state or an entangled two-qubits state is transmitted from a sender (Alice) to a …

Fusing the ideas of bidirectional controlled teleportation and joint remote state preparation,
we put forward a protocol for implementing five-party bidirectional controlled joint remote …

We present a scheme for asymmetric quantum-information splitting, where a sender
distributes asymmetrically a quantum secret (quantum state) to distant partners in a network …

Recently, a genuine four-qubit entangled state∣ χ 00⟩ 3214 has been proposed [Y. Yeo
and WK Chua, Phys. Rev. Lett. 96, 060502 (2006)]. This state has many interesting …

We investigate two-party quantum teleportation through noisy channels for multi-qubit
Greenberger–Horne–Zeilinger (GHZ) states and find which state loses less quantum …

This paper presents a new scheme of bidirectional controlled quantum teleportation (BCQT)
through a ten-qubit entangled channel. As two users, Alice and Bob can transfer an arbitrary …

We propose a scheme for multiparty hierarchical quantum-information splitting (QIS) with a
multipartite entangled state, where a boss distributes a secret quantum state to two grades of …

We propose a protocol Dn for faithfully teleporting an arbitrary n-qudit state with the tensor
product state (TPS) of n generalized Bell states (GBSs) as the quantum channel. We also put …

In this paper, we present a quantum key agreement (QKA) protocol with non-maximally
entangled four-qubit cluster states. In our scheme, each participant carries out two unitary …

We propose several schemes for the joint remote preparation of four-qubit cluster-type states
with real coefficients and complex coefficients by using six Einstein–Podolsky–Rosen (EPR) …
