Quantum Key Distribution over 100 km underwater optical fiber assisted by a Fast-Gated Single-Photon Detector
Domenico Ribezzo, Mujtaba Zahidy, Gianmarco Lemmi +10
Nowadays Quantum Key Distribution represents the most mature quantum technology, and multiple countries as well as private institutions are building their quantum network. However,…
Protective Measurement -- a new quantum measurement paradigm: detailed description of the first realisation
Enrico Rebufello, Fabrizio Piacentini, Alessio Avella +9
We present a detailed description of the experiment realising for the first time a protective measurement, a novel measurement protocol which combines weak interactions with a ``pr…
Hong-Ou-Mandel interference between independent III-V on silicon waveguide integrated lasers
C. Agnesi, B. Da Lio, D. Cozzolino +12
The versatility of silicon photonic integrated circuits has led to a widespread usage of this platform for quantum information based applications, including Quantum Key Distributio…
Investigating the Effects of the Interaction Intensity in a Weak Measurement
Fabrizio Piacentini, Alessio Avella, Marco Gramegna +6
Measurements are crucial in quantum mechanics, in fundamental research as well as in applicative fields like quantum metrology, quantum-enhanced measurements and other quantum tech…
Determining the Quantum Expectation Value by Measuring a Single Photon
F. Piacentini, A. Avella, E. Rebufello +9
Quantum mechanics, one of the keystones of modern physics, exhibits several peculiar properties, differentiating it from classical mechanics. One of the most intriguing is that var…
Anomalous Weak Values and the Violation of a Multiple-measurement Leggett-Garg Inequality
Alessio Avella, Fabrizio Piacentini, Michelangelo Borsarelli +7
Quantum mechanics presents peculiar properties that, on the one hand, have been the subject of several theoretical and experimental studies about its very foundations and, on the o…
Towards correcting atmospheric beam wander via pump beam control in a down conversion process
Christopher J. Pugh, Piotr Kolenderski, Carmelo Scarcella +2
Correlated photon pairs produced by a spontaneous parametric down conversion (SPDC) process can be used for secure quantum communication over long distances including free space tr…
Backflash light characterization to prevent QKD zero-error hacking
A. Meda, I. P. Degiovanni, A. Tosi +3
Single photon avalanche diodes (SPADs) are the most commercially diffused solution for single-photon counting in quantum key distribution (QKD) applications. However, the secondary…
Time and spectrum-resolving mutiphoton correlator for 300-900 nm
Kelsey D. Johnsen, Piotr Kolenderski, Carmelo Scarcella +3
We demonstrate a single-photon sensitive spectrometer in the visible range, which allows us to perform time-resolved and multi-photon spectral correlation measurements. It is based…
Time-resolved double-slit experiment with entangled photons
Piotr Kolenderski, Carmelo Scarcella, Kelsey D. Johnsen +7
The double-slit experiment strikingly demonstrates the wave-particle duality of quantum objects. In this famous experiment, particles pass one-by-one through a pair of slits and ar…
Inherent polarization entanglement generated from a monolithic semiconductor chip
Rolf T. Horn, Piotr Kolenderski, Dongpeng Kang +9
Creating miniature chip scale implementations of optical quantum information protocols is a dream for many in the quantum optics community. This is largely because of the promise o…
An extremely low-noise heralded single-photon source: a breakthrough for quantum technologies
