Don't be scared of actually reading the paper “Scalable Networks for Simultaneous Pairwise Quantum Key Distribution via Entanglement-Based Time-Bin Coding”!

With quantum computers breaking most if not all of our currently used public-key cryptography, offers a secure alternative. “Secure” as in information-theoretically secure, i.e., unbreakable.

For anybody interested in the current developments in this field, the research group I work at published an interesting article about their current work in the journal Quantum:

@IzzyOnDroid Ne, nicht Tethering über Mobile Daten. Ich schließe einfach nur das Handy per USB an und wähle dann in der aufploppenden Benachrichtigung USB-Tethering aus. Anschließend teilt mein Handy seine WLAN-Verbindung über USB, in weniger als 10 Sekunden Arbeit!

Am aufwendigsten ist es da noch, den USB-Stecker richtig rum reinzustecken. Probier das Tethering mal aus!

@IzzyOnDroid Was ich in letzter Zeit immer an Laptops ohne Ethernet mache, bei denen das WLAN aus irgendeinem Grund nicht läuft: USB-Tethering vom Android. Funktioniert erstaunlich oft! (Bisher eigentlich immer)

Für das nächste Mal, bevor du wieder ein Restore wagst ;)

Noether BTW was one of the greatest mathematical physicists in history. Her insights underpin much of modern day fundamental physics. The unifying idea behind linear & angular momentum conservation? Noether’s theorem. Scandal that she’s not more famous en.m.wikipedia.org/wiki/Emmy_N

@Blort Oh, I'm not too much into post-quantum cryptography, so I can't really say how good our chances are there. Still I'm optimistic about it, since it's a topic researched _a lot_ all around the globe. I think we'll be able to play the cat and mouse game for some time and invent new mathematical problems that at least for the time being act as trapdoor function, until we find a proper one. Sure, there's still the problem about recorded encrypted data.

@IzzyOnDroid That's the most important thing. Thanks for all you do!

@wildeagle5 Nice to meet you!

I also had some basic classes in quantum mechanics, but stuff like 2 photons interferring even if they are at completely different places still blows my mind.

It's called ”Two-Photon-Interference according to “, if you want to look it up. It's quite important in our system, as that ensures that Alice and Bob note the same 0 or 1 bit after the photons passing the interferometers.

Nice to see you, too, @IzzyOnDroid! It's amazing to see what you're all doing for F-Droid these days!

@nixfreak Well, they lack some comfort of centralized networks, but I think they are the only way forward. Thanks to cryptography quite some comfort can be restored or even improved, e.g., by using Shamir's Secret Sharing to backup your Briar account across your friends.

@rysiek Yeah, just found out how to feature them from my account 🙂

Thanks to @rysiek for pointing me towards infosec.exchange without knowing it. After months of following people through various different browser tabs I figured that it's a good thing to finally open an account on this fediverse thing here.

Hey all! I just joined the fediverse and found that it's a nice thing to start with an .

My name is Nico Alt, you might don't know me but if you do, it's most probably due to the stuff I did at and . Currently I'm not active there but instead focus on university/#physics stuff where I contribute my little part to (multi-party time-bin coding, to be more specific). Other interests are and , feel free to talk to me about them!
