Heralded single photon sources for QKD applications
M. Schiavon, G. Vallone, F. Ticozzi +1
Single photon sources (SPS) are a fundamental building block for optical implementations of quantum information protocols. Among SPSs, multiple crystal heralded single photon sourc…
Source-device-independent Ultra-fast Quantum Random Number Generation
Davide G. Marangon, Giuseppe Vallone, Paolo Villoresi
Secure random numbers are a fundamental element of many applications in science, statistics, cryptography and more in general in security protocols. We present a method that enable…
Interference at the Single Photon Level Along Satellite-Ground Channels
Giuseppe Vallone, Daniele Dequal, Marco Tomasin +5
Quantum interference arising from superposition of states is a striking evidence of the validity of Quantum Mechanics, confirmed in many experiments and also exploited in applicati…
Experimental single photon exchange along a space link of 7000 km
Daniele Dequal, Giuseppe Vallone, Davide Bacco +4
Extending the single photon transmission distance is a basic requirement for the implementation of quantum communication on a global scale. In this work we report the single photon…
Strong measurements give a better direct measurement of the quantum wave function
Giuseppe Vallone, Daniele Dequal
Weak measurements have thus far been considered instrumental in the so-called direct measurement of the quantum wavefunction [Nature (London) 474, 188 (2011)]. Here we show that di…
