Experiment opens the door to multi-party quantum communication (Update)
In the world of quantum science, Alice and Bob have been talking to one another for years. Charlie joined the conversation a few years ago, but now by enforcing the space-like separation of the three parties, ...
Quantum physics secures new cryptography scheme
The way we secure digital transactions could soon change. An international team has demonstrated a form of quantum cryptography that can protect people doing business with others they may not know or trust ...
NSA pursues quantum technology
In this month's issue of Physics World, Jon Cartwright explains how the revelation that the US National Security Agency (NSA) is developing quantum computers has renewed interest and sparked debate on just how far ahead ...
New approach enhances quantum-based secure communication
University of Calgary scientists have overcome an 'Achilles' heel' of quantum-based secure communication systems, using a new approach that works in the real world to safeguard secrets.
Engineers achieve first airplane to ground quantum key distribution exchange
Making quantum cryptography truly secure
Quantum key distribution (QKD) is an advanced tool for secure computer-based interactions, providing confidential communication between two remote parties by enabling them to construct a shared secret key ...
Researchers weight safety of quantum cryptology
Scientists in Belgium and Spain have proved for the first time that new systems of quantum cryptology are much safer than current security systems. The study was published in the journal Nature Communications.
