In principle, quantum key distribution (QKD) offers information-theoretic security based on
the laws of physics. In practice, however, the imperfections of realistic devices might …

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 …

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 …

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

Quantum Information Theory is an area of physics which studies both fundamental and
applied issues in quantum mechanics from an information-theoretical viewpoint. The …

Abstract “Device-independent” not only represents a relaxation of the security assumptions
about the internal working of the quantum devices, but also can enhance the security of the …

Despite enormous theoretical and experimental progress in quantum cryptography, the
security of most current implementations of quantum key distribution is still not rigorously …

Quantum cryptography achieves a formidable task—the remote distribution of secret keys by
exploiting the fundamental laws of physics. Quantum cryptography is now headed towards …

Device-independent quantum key distribution (DIQKD) represents a relaxation of the
security assumptions made in usual quantum key distribution (QKD). As in usual QKD, the …
