Quantum networks play an extremely important role in quantum information science, with
application to quantum communication, computation, metrology, and fundamental tests. One …

An optical quantum memory is a device that can store photonic quantum information and
release it after a controlled time. It is an essential component for overcoming channel losses …

In order to bring quantum networks into the real world, we would like to determine the
requirements of quantum network protocols including the underlying quantum hardware …

Quantum key distribution—exchanging a random secret key relying on a quantum
mechanical resource—is the core feature of secure quantum networks. Entanglement-based …

If a photon interacts with a member of an entangled photon pair via a Bell-state
measurement (BSM), its state is teleported over principally arbitrary distances onto the pair's …

Quantum information and communication technology will lead us to the new era of ultra‐fast
and absolute‐secure networks. With the emergence of quantum supremacy on the horizon …

Quantum teleportation is essential for many quantum information technologies, including
long-distance quantum networks. Using fiber-coupled devices, including state-of-the-art low …

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

Time-and number-resolved photon detection is crucial for quantum information processing.
Existing photon-number-resolving (PNR) detectors usually suffer from limited timing and …

We argue that long optical storage times are required to establish entanglement at high
rates over large distances using memory-based quantum repeaters. Triggered by this …
