How can one detect entanglement between multiple optical paths sharing a single photon? We address this question by proposing a scalable protocol, which only uses local measurements where single photon detection is combined with small displacement operations. The resulting entanglement witness does not require postselection, nor assumptions about the photon number in each path. Furthermore, it guarantees that entanglement lies in a subspace with at most one photon per optical path and reveals genuinely multipartite entanglement.

Measurement-device–independent quantum key distribution (MDIQKD) represents a valid alternative for quantum cryptography. It requires fewer assumptions for security than standard prepare-and-measure schemes, while its implementation is less demanding than fully device-independent protocols.

Harnessing nonlinearities strong enough to allow two single photons to interact with one another is not only a fascinating challenge but is central to numerous advanced applications in quantum information science. Currently, all known approaches are extremely challenging although a few have led to experimental realisations with attenuated classical laser light.

Quantum Key Distribution (QKD) is the first commercial application in the field of quantum information science, with the first routine applications in government and financial sectors and with successful demonstrations of trusted node networks. Today, the main goal is efficient long-range key distribution via either a network structure called 'quantum repeaters' or via satellite, with a view to enabling global secure communication.

Bit commitment is a fundamental cryptographic primitive in which Bob wishes to commit a secret bit to
Alice. Perfectly secure bit commitment between two mistrustful parties until recently was thought to be
impossible even when the parties exchange quantum messages.

However, Kent recently showed that perfect security is indeed theoretically possible, if Alice and Bob split
