The paper I co-authored (“A Critical Analysis of Deployed Use Cases for Quantum Key Distribution and Comparison with Post-Quantum Cryptography”) was accepted for publication by “EPJ Quantum Technology” today. 😊

You can find the preprint here, Nick will eventually update it with the final changes.

In short: We looked into existing use-cases for
#QuantumKeyDistribution and whether they make any sense and did so as a joint team between people with a QKD-background and cryptographers who started out very critical of QKD. (I’m firmly in the latter camp.)

My personal summary (though some of my co-authors won’t share it to this extend):
#QKD is bullshit and not useful for practical purposes as it stands.

The NCSC’s advisory deadline of 2035 for organisations to introduce quantum-safe algorithms is too late, according to some industry insiders.

🌟 EduQ: our DIY Quantum Learning platform for the mass 🔐✨

🎉 Just demoed our hands-on quantum learning platform at a cutting-edge French Engineering school ! EduQ makes quantum accessible to engineers without physics backgrounds through applied experiments and research

➜ Live-generated entangled photons (g²(0) < 1 = quantum-proof!)
➜ Quantum comms detect eavesdroppers automatically — like a built-in cyber alarm!
➜ Hybrid systems (quantum + post-quantum crypto) = ultra-secure future.

EduQ bridges theory and real-world impact to redefine secure communications. One photon at a time.

Guy asks about what would happen if lattices and codes got broken.

After people panel outlines some non great but workable alternatives, asks about
#QKD. Immidiately gets shot down.

It's bullshit and all cryptographers know it!

UK NCSC:

Publicly states that (asymmetric) post quantum crypto is the best response to the quantum thread, with purely symmetric options being an alternative for some special circumstances.

No mention of
#QKD. Good!

UK cybersecurity agency National Cyber Security Centre is recommending that organisations start replacing existing asymmetric public key cryptosystems with post-quantum cryptography (PQC) alternatives to defend themselves against quantum computers

I was just ranting about #QKD in a chat with someone, when I compared quantum-resiliant cryptography with quantum key distribution like this, and noticed that I really like this summary:

If you want to go 500 meter down the street you can either take your bike or call a helicopter to your place, have it hover over your home, climb up a rope ladder, have it fly you those 500 meters and dis-rope.
Both of these get you to your destination, but one of them is faster, cheaper, less complicated, relying on more established infrastructure, scales better and is just about superior in every relevant regard. And it’s not the helicopter/QKD.

I thought sure I had shared this in December, but I can't find it - researchers at Northwestern University demonstrated for the first time ever #QKD (quantum key distribution; in this case the entanglement-based flavor, as opposed to the prepare & measure flavor) traffic over a fiber optic cable also carrying live Internet traffic, proving there's a path towards quantum and classical networks sharing a unified physical infrastructure. This will make adoption *MUCH* easier than having to roll out dedicated infrastructure for the #quantum Internet. news.northwestern.edu/stories/

@Em0nM4stodon not only is it good opsec but for biz in particular they want and need secure comms - just to conduct business #alice and bob #bb84 #pki #qkd #5g security #evercookie

somehow I think I missed this announcement back in October: China is launching two or three #quantum communications satellites into LEO this year. The satellites build upon the pioneering Mozi satellite that China launched in 2016 to test #QKD and entanglement in space.

With national authorities and experts underlining the immediate risk from “Harvest Now, Decrypt Later” () attacks, the financial sector must begin mitigating the associated security risks to financial assets. Major institutions are already leading the way with a dual quantum-safe strategy that combines Post-Quantum Cryptography () and Quantum Key Distribution (). Learn more: ilphotonics.com/pqc-and-qkd/

🎓 Ready to start your #Quantum learning journey?

The first learning units in our new #QuantumTech #eAcademy are out, including an intro block on Quantum Algebra and units on IBM Qiskit and ETSI standard key exchange APIs!

And many more units are in the works, covering #QuantumCommunications, #QuantumComputing, #QKD, simulation, resources, sensing and metrology, standardisation.

Use our interactive metro map to access units and to get an overview of what’s yet to come: wiki.geant.org/display/NETDEV/

GÉANT Quantum Tech eAcademy - December 2024

The interactive metro map is a visual way to help you follow your self-paced training, depending on your interests. These are some tips to follow the map:

- We highly recommend starting your quantum learning journey from the introductory block on Quantum Algebra and in the right sequence, to then proceed in the preferred direction after the exchange point marked by the big circle.
- A circle in a station means this is a Moodle course in the eAcademy / A square means this is a document or an external website.
- A station with the font highlighted is available / A station with the font grayed-out means it’s not published yet.
- Some stations can belong to more than one line.

Recently, two groups published exciting results using free-space optical links for with technology. In one paper, the authors report on a study of the effect of atmospheric turbulence on finite-size decoy-state BB84 quantum key distribution (). In another collaboration, the team demonstrated a QKD system designed for full daylight operation at 1550 nm. Learn more: ilphotonics.com/practical-free
