Thirty years after it was first proposed, quantum teleportation remains one of the most
important protocols in quantum information and quantum technologies, enabling the …

Quantum cryptography is arguably the fastest growing area in quantum information science.
Novel theoretical protocols are designed on a regular basis, security proofs are constantly …

Concerted efforts are underway to establish an infrastructure for a global quantum Internet to
realise a spectrum of quantum technologies. This will enable more precise sensors, secure …

Quantum key distribution (QKD) is a family of protocols for growing a private encryption key
between two parties. Despite much progress, all ground-based QKD approaches have a …

Global-scale quantum communication links will form the backbone of the quantum internet.
However, exponential loss in optical fibres precludes any realistic application beyond few …

Quantum technology is an emergent and potentially disruptive discipline, with the ability to
affect many human activities. Quantum technologies are dual-use technologies, and as such …

Global quantum networks for secure communication can be realized using large fleets of
satellites distributing entangled photon pairs between ground-based nodes. Because the …

The future envisaged global-scale quantum-communication network will comprise various
nodes interconnected via optical fibers or free-space channels, depending on the link …
