Ghost imaging with intense fields from chaotically-seeded parametric downconversion
E. Puddu, A. Andreoni, I. P. Degiovanni +2
We present the first experimental demonstration of ghost imaging realized with intense beams generated by a parametric downconversion interaction seeded with pseudo-thermal light.…
Reduced Deadtime and Higher Rate Photon-Counting Detection using a Multiplexed Detector Array
S. Castelletto, I. P. Degiovanni, V. Schettini +1
We present a scheme for a photon-counting detection system that can be operated at incident photon rates higher than otherwise possible by suppressing the effects of detector deadt…
Optimizing single-photon-source heralding efficiency at 1550 nm using periodically poled lithium niobate
S. Castelletto, I. P. Degiovanni, V. Schettini +1
We explore the feasibility of using high conversion-efficiency periodically-poled crystals to produce photon pairs for photon-counting detector calibrations at 1550 nm. The goal is…
Reply to Comment on "Quantum dense key distribution"
I. P. Degiovanni, I. Ruo Berchera, S. Castelletto +4
In this Reply we propose a modified security proof of the Quantum Dense Key Distribution protocol detecting also the eavesdropping attack proposed by Wojcik in his Comment.
Quantum dense key distribution
I. P. Degiovanni, I. Ruo Berchera, S. Castelletto +4
This paper proposes a new protocol for quantum dense key distribution. This protocol embeds the benefits of a quantum dense coding and a quantum key distribution and is able to gen…
Coupling Efficiencies in Single Photon On-Demand Sources
Stefania Castelletto, I. P. Degiovanni, Michael Ware +1
Many quantum computation and communication schemes require, or would significantly benefit from, true sources of single photon on-demand (SPOD). Unfortunately, such sources do not…
