All-in-fiber dynamic orbital angular momentum mode sorting
Alvaro Alarcón, Santiago Gómez, Daniel Spegel-Lexne +5
The orbital angular momentum (OAM) spatial degree of freedom of light has been widely explored in many applications, including telecommunications, quantum information and light-bas…
Dynamic generation of photonic spatial quantum states with an all-fiber platform
A. Alarcón, J. Argillander, D. Spegel-Lexne +1
Photonic spatial quantum states are a subject of great interest for applications in quantum communication. One important challenge has been how to dynamically generate these states…
Certification of genuine time-bin and energy-time entanglement with integrated photonics
Francesco B. L. Santagiustina, Costantino Agnesi, Alvaro Alarcón +4
Time-bin (TB) and energy-time (ET) entanglement are crucial resources for long-distance quantum information processing. Recently, major efforts have been made to produce compact hi…
Quantum random number generation based on a perovskite light emitting diode
Joakim Argillander, Alvaro Alarcón, Chunxiong Bao +4
The recent development of perovskite light emitting diodes (PeLEDs) has the potential to revolutionize the fields of optical communication and lighting devices, due to their simpli…
A tunable quantum random number generator based on a fiber-optical Sagnac interferometer
Joakim Argillander, Alvaro Alarcón, Guilherme B. Xavier
Quantum random number generators (QRNG) are based on the naturally random measurement results performed on individual quantum systems. Here, we demonstrate a branching-path photoni…
Few-mode-fiber technology fine-tunes losses of quantum communication systems
A. Alarcón, J. Argillander, G. Lima +1
A natural choice for quantum communication is to use the relative phase between two paths of a single-photon for information encoding. This method was nevertheless quickly identifi…
