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 …

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

Random numbers are a fundamental resource in science and engineering with important
applications in simulation and cryptography. The inherent randomness at the core of …

Physical layer security (PHY-security) takes the advantages of channel randomness nature
of transmission media to achieve communication confidentiality and authentication. Wiretap …

Key generation from the randomness of wireless channels is a promising alternative to
public key cryptography for the establishment of cryptographic keys between any two users …

Quantum key distribution (QKD) systems often rely on polarization of light for encoding, thus
limiting the amount of information that can be sent per photon and placing tight bounds on …

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 …

The advanced notebooks, mobile phones, and Internet applications in today's world that we
use are all entrenched in classical communication bits of zeros and ones. Classical Internet …
