Now, Eleni Diamanti on Practical Secure Quantum Communications #JapanEUWorkshop #LTQI

Eleni Diamanti: The current solution to secure network links: Symmetric + Asymmetric cryptography. Recent development to fight the threat of quantum computers: postquantum cryptography. Quantum cryptography offers the advantage to be future proof #LTQI

Eleni Diamanti: REal security will have to combine the the use of classical and quantum cryptography. nature.com/articles/nphys…
#LTQI #JapanEUWorkshop

Eleni Diamanti: Current pactical challenges of QKD: Photonic integration, telecom network integration, Mesh trusted node networks and ground to satellite links. Solving these will also be useful for further quantum technologies #LTQI #JapanEUWorkshop

Eleni Diamanti wants to extend the quantum advantage of QKD to other functionality. The problem: these protocol are confined in theoretical computer science literature and need to be adapted to real life imperfections and realistic resources #LTQI #JapanEUWorkshop

Eleni Diamanti adapted coin flipping protocol to the imperfection of a discret QKD-like set-up. You need to include the possibility of aborting, but it works

Eleni Diamanti also adapted Wiesner’s unforgeable quantum money, with a new protocol allowing classical verification, using weak coherent state arxiv.org/abs/1705.01428 / nature.com/articles/s4153…

Eleni Diamanti current work: collaborating with @lkb_lab to do quantum money with an actual quantum memory. #LTQI #JapanEUWorkshop

@lkb_lab Eleni Diamanti also works on network protocols, like verifying the distribution of multipartite states. arxiv.org/abs/1112.5064 journals.aps.org/prl/abstract/1… and arxiv.org/abs/1611.04772 nature.com/articles/ncomm… #LTQI #JapanEUWorkshop

@lkb_lab Eleni Diamanti also works in communication complexity, when different parties need to perform a joint task minimizing their communications. There are many applications, with quantum advantage, but the latter is hard to demonstrate

@lkb_lab Eleni Diamanti: The ardnes comes from the difficulty of preparing fingerprint states ∑(-1)^f_i|i⟩. Norbert Lutkenhaus found a mapping tto cehernt states. It allows for implementations arxiv.org/abs/1609.09600 journals.aps.org/pra/abstract/1… #LTQI

@lkb_lab Eleni Diamanti: the same techniques can also be used to show quantum superiority in the verification of NP-complete problems arxiv.org/abs/1711.02200 #LTQI #JapanEUWorkshop
