Quantum key distribution (QKD), allows two distant parties to share encryption keys with
security based on physical laws. Experimentally, QKD has been implemented via optical …

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

Quantum information is a rapidly advancing area of interdisciplinary research. It may lead to
real-world applications for communication and computation unavailable without the …

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 …

Csiszár and Körner's book is widely regarded as a classic in the field of information theory,
providing deep insights and expert treatment of the key theoretical issues. It includes in …

Two separated observers, by applying local operations to a supply of not-too-impure
entangled states (eg, singlets shared through a noisy channel), can prepare a smaller …

We review the current status of single-photon-source and single-photon-detector
technologies operating at wavelengths from the ultraviolet to the infrared. We discuss …

Quantum cryptography exploits principles of quantum physics for the secure processing of
information. A prominent example is secure communication, ie, the task of transmitting …
