This tutorial reviews fundamental contributions to information security. An integrative
viewpoint is taken that explains the security metrics, including secrecy, privacy, and others …

The appealing feature of quantum key distribution (QKD), from a cryptographic viewpoint, is
the ability to prove the information-theoretic security (ITS) of the established keys. As a key …

The speed at which two remote parties can exchange secret keys in continuous-variable
quantum key distribution (CV-QKD) is currently limited by the computational complexity of …

We present a compactly integrated, 625 MHz clocked coherent one-way quantum key
distribution system which continuously distributes secret keys over an optical fibre link. To …

Error correction is a significant step in postprocessing of continuous-variable quantum key
distribution system, which is used to make two distant legitimate parties share identical …

Here, we demonstrate that a practical continuous-variable quantum key distribution (QKD)
protocol relying on the Gaussian modulation of coherent states features secret key rates that …

Quantum key distribution (QKD) is a quantum-proof key-exchange scheme which is fast
approaching the communication industry. An essential component in QKD is the information …

We develop a new approach for asymmetric LDPC-based information reconciliation in order
to adapt to the current channel state and achieve better performance and scalability in …

It is widely accepted in the quantum cryptography community that interactive information
reconciliation protocols, such as cascade, are ineffcient due to the communication overhead …

Secure distribution of high-speed digital encryption/decryption keys over a classical fiber
channel is strongly pursued for realizing perfect secrecy communication systems. However …
