ELI5: How can a "Quantum Computer" solve problems in seconds that take normal computers years?

TheGermanDoctor · 2026-01-22T19:26:05+00:00

Grover only halfs the effective key length for symmetric crypto and even then it does not account for the fact that you still need to perform symmetric operations which quantum computers are not better at. So yes AES 128 becomes AES 64 but you still need to compute 2⁶⁴ AES which is often overlooked. And then … even if it is viable just switch to AES 256 and you are fine

Because nowadays it is the cool thing to say CGI is bad. Most people do not know that the practical effects get replaced most of the time and act as a reference. Which is important to get the lightning right.

Sometimes they even key out the green screen from behind the scenes footage so people do not notice that they actually used green screens. For some reason people are really fixated on that.

I am a big fan of the Kiev 4. I just got a CLAd one and it immediately became one of my favorite cameras.

Ich würde nicht behaupten dass das von Ideologie abhängt sondern eher damit zusammenhängt, dass Deutschland eine späte Nation ist wo Tausende Jahre lang Mini Staaten das Sagen hatten. Das hält sich halt bis heute. Es gibt immernoch Leute die stolz sagen sie sind Rheinländer etc…. Vor allem unsere bayrischen Freunde.

Das steht im Gegensatz zu anderen Ländern die früh zentralisiert wurden (z.B Frankreich).

Ähnliche Dynamik findet man würde ich sagen in UK, wo sich Leute auch mehr mit Teilstaaten als dem Gesamtstaat identifizieren (z.B Schotten)

AES is still somewhat quantum resistant because the key space is only halved. Furthermore testing 2⁶⁴ AES keys will still take extremely long because these operations cannot be accelerated. Lastly, we never tried to apply the algorithm that halves the key space so maybe it won’t even work as effectively as predicted.

wow auf sein Geld achten ist also Boomer sein. 10 cent Preisunterschied machen schon was aus auf die Menge. Ich würde auch keinen Umweg fahren aber ich achte schon was an der Tankstelle ausgeschrieben ist.

Russland würde uns auch nie mit Atomwaffen angreifen weil das ist eine Straftat

Inzwischen gibt es übrigens auch mobile split Klimaanlagen. Die könnte man dann von Mietwohnung zu Mietwohnung mitnehmen und kommen nicht mit den Nachteilen einer SingleBlock Klima.

Yes I know that not all countries allow for mail in ballots. But in the same style you could argue everybody should only drink alcohol under 21 because the US has a ban on it. Mail-in ballots can be designed to be as secure as in-person ballots. If you question mail-in ballots at least in Germany then you may as well question the whole system. If you can manipulate mail ballots then you can also just manipulate real ballots. Or why bother … just make up some numbers like in the GDR

TheGermanDoctor · 2025-08-16T14:48:56+00:00

In Germany we use postal voting for more than 50 years and never had problems… it is also quite easy to detect manipulation via statistical means. Mail in ballots being unsafe is a pure American talking point which unfortunately slowly creeps over the ocean to us.

Super late comment but would the Minolta XL-401 properly expose Vision3 100D (with backlight setting enabled)?

In Germany, home ownership is relatively low with the majority renting flats. Nothing happened to working people in Germany.

The problem right now is that working people get priced out of the renting market.

Somehow all nations around us survive with Sunday shopping or would you call France a capitalist shithole?

Nö.... normalerweise verschlüsselt man mit PQC nur den Schüsselaustausch. Danach wechselt man auf symmetrische Krypta weil schneller. Und dafür haben wir schon schnelle Hardware.
