A quantum internet is the holy grail of quantum information processing, enabling the
deployment of a broad range of quantum technologies and protocols on a global scale …

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 communications promise to revolutionize the way information is exchanged and
protected. Unlike their classical counterpart, they are based on dim optical pulses that …

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 computation and quantum communication are expected to provide users with
capabilities inaccessible by classical physics. However, scalability to larger systems with …

Quantum entanglement enables important computing applications such as quantum key
distribution. Based on quantum entanglement, quantum networks are built to provide long …

Long-distance quantum communication requires quantum repeaters to overcome photon
loss in optical fibers. Here we demonstrate a repeater node with two memory atoms in an …

Variations of phase-matching measurement-device-independent quantum key distribution
(PM-MDI QKD) protocols have been investigated before, but it was recently discovered that …

Quantum channels enable the implementation of communication tasks inaccessible to their
classical counterparts. The most famous example is the distribution of secret key. However …

We review recent results on the simulation of quantum channels, the reduction of adaptive
protocols (teleportation stretching), and the derivation of converse bounds for quantum and …
