Hyperentanglement is a promising resource in quantum information processing with its high
capacity character, defined as the entanglement in multiple degrees of freedom (DOFs) of a …

We present two efficient quantum key distribution schemes over two different collective-
noise channels. The accepted hypothesis of collective noise is that photons travel inside a …

Following some ideas of the quantum secret sharing (QSS) protocol (2008, Phys. Lett. A
372, 1957), we propose an efficient quantum private comparison (QPC) protocol for …

We present an efficient quantum repeater protocol that uses coupled systems of quantum-
dot spins and optical microcavities, in which the spatial entanglement of a photon system …

Hyperentanglement is a promising resource in quantum information processing, especially
for increasing the channel capacity of long-distance quantum communication …

We propose a heralded quantum repeater protocol based on the general interface between
the circularly polarized photon and the quantum dot embedded in a double-sided optical …

Hyperentanglement has attracted much attention due to its fascinating applications in
quantum communication. However, it is impossible to purify a pair of photon systems in a …

In this paper, we present a QKA protocol with the block transmission of EPR pairs. There are
several advantages in this protocol. First, this protocol can guarantee both the fairness and …

We present two robust quantum secure direct communication (QSDC) schemes with a
quantum one-time pad over a collective-noise channel. Each logical qubit is made up of two …
