Cryptography is a discipline that studies encryption, decryption and related techniques in a
number of fields, including information security, computer science and mathematics. Its aim …

Niobium nitride (NbN) is widely used in the production of superconducting nanowire single-
photon detectors (SNSPDs) due to its high superconducting transition temperature and …

Photonic integrated circuits (PICs) have long been considered as disruptive platforms that
revolutionize optics. Building on the mature industrial foundry infrastructure for electronic …

A limitation of free-space optical communications is the ease with which the information can
be intercepted. This limitation can be overcome by hiding the information within background …

Superconducting nanowire single-photon detectors are an enabling technology for modern
quantum information science and are gaining attractiveness for the most demanding photon …

We report on the superconducting properties of amorphous NbGe thin films of thickness in
the range from 50 to 10 nm, to assess and compare their characteristics for single-photon …

We propose a fast, satellite-based, on-demand entanglement resupply protocol which
leverages entangled pairs exchanged in advance between satellites and ground stations. At …

At the intersection of technological evolution and escalating computational demand, the role
of optics is reemerging as a transformative force in the field of computing. This article …

Quantum key distribution (QKD) is a secure communication method that relies on the
inherent randomness of quantum mechanics to ensure information-theoretic security. The …

We investigate the growth conditions for thin (${\leqslant} 200$ nm) sputtered aluminum
films. These coatings are needed for various applications, eg for advanced manufacturing …
