The science of quantum information has arisen over the last two decades centered on the
manipulation of individual quanta of information, known as quantum bits or qubits. Quantum …

All our former experience with application of quantum theory seems to say that what is
predicted by quantum formalism must occur in the laboratory. But the essence of quantum …

Finally, here is a modern, self-contained text on quantum information theory suitable for
graduate-level courses. Develo** the subject'from the ground up'it covers classical results …

Quantum secure direct communication (QSDC) attracts much attention for it can transmit
secret messages directly without sharing a key. In this article, we propose a one-step QSDC …

An unknown quantum state‖ φ> can be disassembled into, then later reconstructed from,
purely classical information and purely nonclassical Einstein-Podolsky-Rosen (EPR) …

The entanglement of a pure state of a pair of quantum systems is defined as the entropy of
either member of the pair. The entanglement of formation of a mixed state ρ is the minimum …

Entanglement purification protocols (EPPs) and quantum error-correcting codes (QECCs)
provide two ways of protecting quantum states from interaction with the environment. In an …

The upcoming fifth generation (5G) of wireless networks is expected to lay a foundation of
intelligent networks with the provision of some isolated artificial intelligence (AI) operations …

Photonic quantum technologies represent a promising platform for several applications,
ranging from long-distance communications to the simulation of complex phenomena …

We report on a high-intensity source of polarization-entangled photon pairs with high
momentum definition. Type-II noncollinear phase matching in parametric down conversion …
