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 …

Quantum information processing exploits the quantum nature of information. It offers
fundamentally new solutions in the field of computer science and extends the possibilities to …

Quantum Teleportation is the key communication functionality of the Quantum Internet,
allowing the “transmission” of qubits without the physical transfer of the particle storing the …

Quantum communication holds promise for unconditionally secure transmission of secret
messages and faithful transfer of unknown quantum states. Photons appear to be the …

Most quantum communication tasks need to rely on the transmission of quantum signals
over long distances. Unfortunately, transmission of such signals is most often limited by …

Quantum networks build on entanglement and quantum measurement to achieve tasks that
are beyond the reach of classical systems. Using quantum effects, we can detect the …

It is impossible to unambiguously distinguish the four Bell states in polarization, resorting to
linear optical elements only. Recently, the hyperentangled Bell state, the simultaneous …

Quantum networks will enable the implementation of communication tasks with qualitative
advantages with respect to the communication networks known today. While it is expected …

We present a stack model for breaking down the complexity of entanglement-based
quantum networks. More specifically, we focus on the structures and architectures of …

Quantum repeaters will be critical to quantum communication and quantum computation.
Here, we describe a mechanism that permits the creation of entanglement between two …
