High-speed Source-Device-Independent Quantum Random Number Generator on a Chip
Tommaso Bertapelle, Marco Avesani, Alberto Santamato +11
A wide range of applications require, by hypothesis, to have access to a high-speed, private, and genuine random source. Quantum Random Number Generators (QRNGs) are currently the…
Optimal focusing conditions for bright spontaneous parametric down-conversion sources
Lorenzo Coccia, Alberto Santamato, Giuseppe Vallone +1
Optimizing the brightness of a spontaneous parametric down conversion (SPDC) source is an important task for many quantum information applications. We investigate the optimal focus…
The eight-port homodyne detector: the effect of imperfections on quantum random number generation and on detection of quadratures
Alberto Barchielli, Alberto Santamato
The eight-port homodyne detector is an optical circuit designed to perform the monitoring of two quadratures of an optical field, the signal. By using quantum Bose fields and quant…
Full daylight quantum-key-distribution at 1550 nm enabled by integrated silicon photonics
M. Avesani, L. Calderaro, M. Schiavon +16
The future envisaged global-scale quantum communication network will comprise various nodes interconnected via optical fibers or free-space channels, depending on the link distance…
Sub-ns timing accuracy for satellite quantum communications
Costantino Agnesi, Luca Calderaro, Daniele Dequal +7
Satellite quantum communications have rapidly evolved in the past few years, culminating in the proposal, development, and deployment of satellite missions dedicated to quantum key…
Towards Quantum Communication from Global Navigation Satellite System
Luca Calderaro, Costatino Agnesi, Daniele Dequal +7
Satellite-based quantum communication is an invaluable resource for the realization of a quantum network at the global scale. In this regard, the use of satellites well beyond the…
An On-chip Homodyne Detector for Measuring Quantum States and Generating Random Numbers
Francesco Raffaelli, Giacomo Ferranti, Dylan H. Mahler +7
Optical homodyne detection has found use in a range of quantum technologies as both a characterisation tool and as a way to post-selectively generate non-linearities. So far optica…
Gallium Arsenide (GaAs) Quantum Photonic Waveguide Circuits
Jianwei Wang, Alberto Santamato, Pisu Jiang +14
Integrated quantum photonics is a promising approach for future practical and large-scale quantum information processing technologies, with the prospect of on-chip generation, mani…
Optical interferometry in the presence of large phase diffusion
Marco G. Genoni, Stefano Olivares, Davide Brivio +5
Phase diffusion represents a crucial obstacle towards the implementation of high precision interferometric measurements and phase shift based communication channels. Here we presen…
