No-cloning theorem is fundamental for quantum mechanics and for quantum information
science that states an unknown quantum state cannot be cloned perfectly. However, we can …

We present several protocols for joint remote state preparation of a single (two)-quadbit state
with real (or complex) coefficients via a projective or positive operator-valued measure. In …

Quantum information cannot be perfectly cloned, but approximate copies of quantum
information can be generated. Quantum telecloning combines approximate quantum …

Characterization and exploitation of multiple channels between the transmitter and the
receiver in multiple-input multiple-output (MIMO) communications brought a paradigm shift …

In this paper, we investigate generalized remote information concentration as the reverse
process of ancilla-free phase-covariant telecloning (AFPCT) which is different from the …

We investigate the schemes of quantum network teleportation for quantum information
distribution and concentration, which are essential in quantum cloud computation and the …

We propose a method to construct a nondestructive n-qubit Greenberger–Horne–Zeilinger
(GHZ)-state analyzer. The method is applied to any systems in which two-qubit parity gates …

By using a proper positive operator-valued measure (POVM), we present two new schemes
for remote information concentration via four-particle cluster state. It is demonstrated that by …

The previous protocols of remote quantum information concentration were focused on the
reverse process of quantum telecloning of single-qubit states. We here investigate the …

It has been shown that a nearly pure Greenberger–Horne–Zeilinger (GHZ) state could be
distilled from a large (even infinite) number of GHZ-diagonal states that can be obtained by …
