Quantum key distribution (QKD) is the first quantum information task to reach the level of
mature technology, already fit for commercialization. It aims at the creation of a secret key …

Recently, there has been much interest in a new kind of “unspeakable” quantum information
that stands to regular quantum information in the same way that a direction in space or a …

In recent years it has been recognized that properties of physical systems such as
entanglement, athermality, and asymmetry, can be viewed as resources for important tasks …

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 …

Quantum communication employs the counter-intuitive features of quantum physics for tasks
that are impossible in the classical world. It is crucial for testing the foundations of quantum …

Measurement-device-independent quantum key distribution (MDI QKD) is a substantial step
toward practical information-theoretic security for key sharing between remote legitimate …

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 …

Long-distance quantum communication relies on the ability to efficiently generate and
prepare single photons at telecom wavelengths. In many applications these photons must …

We investigate the application of quantum cellular automata in image encryption and
propose a novel quantum gray-scale image encryption algorithm based on one-dimensional …

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 …
