Efficient Hotspot Switching in Plasmonic Nanoantennas using Phase-shaped Laser Pulses controlled by Neural Networks
Alberto Comin, Achim Hartschuh
We present a novel procedure for manipulating the near-field of plasmonic nanoantennas using neural network-controlled laser pulse-shaping. As model systems we numerically studied…
Plasmonics in heavily-doped semiconductor nanocrystals
Francesco Scotognella, Giuseppe Della Valle, Ajay Ram Srimath Kandada +6
Heavily-doped semiconductor nanocrystals characterized by a tunable plasmonic band have been gaining increasing attention recently. Herein, we introduce this type of materials focu…
Feasibility of Logical Bell State Generation in Memory Assisted Quantum Networks
Vladlen Galetsky, Nilesh Vyas, Alberto Comin +1
This study explores the feasibility of utilizing quantum error correction (QEC) to generate and store logical Bell states in heralded quantum entanglement protocols, crucial for qu…
Free space daylight ground-ground QKD in the near-IR
Jan Tepper, Nils Hellerhoff, Alberto Comin
We report a daylight km-range free space QKD demonstration at 850nm obtaining a QBER of 1.9\% and a raw key-rate of 14 kbit/s. We used the BB84 protocol with polarisation encoding…
Compression of Ultrashort Laser Pulses via Gated Multiphoton Intrapulse Interference Phase Scans
Alberto Comin, Richard Ciesielski, Giovanni Piredda +2
Delivering femtosecond laser light in the focal plane of a high numerical aperture microscope objective is still a challenge, despite significant developments in the generation of…
Microscopic view on the ultrafast photoluminescence from photo-excited graphene
Torben Winzer, Richard Ciesielski, Matthias Handloser +3
We present a joint theory-experiment study on ultrafast photoluminescence from photoexcited graphene. Based on a microscopic theory, we reveal two distinct mechanisms behind the oc…
