Minulý rok zverejnil Google novinky o svojom novom kvantovon procesore Willow, schopnom vykonať nejaký nepraktický výpočet, ktorý nikto nevie overiť (lebo klasickému počítaču by trval 10 kvadriliónov rokov).

Priznám sa, že ma to nezaujalo a nič o tom neviem - takých vyhlásení už bolo veľa, aj keď v tomto prípade ľudia ktorým dôverujem (napr. Scot Aaronson) tvrdia, že je to naozaj pôsobivý výkon.

Lenže tento nenápadný článok ma zaujal oveľa viac:

Factoring an integer with three oscillators and a qubit

A common starting point of traditional quantum algorithm design is the notion of a universal quantum computer with a scalable number of qubits.

No, The Chinese Have Not Broken Modern Encryption Systems with a Quantum Computer

The headline is pretty scary: “China’s Quantum Computer Scientists Crack Military-Grade Encryption.”

Shor's algorithm in theory versus in practice.

Let me post this again, because it's great to see that a privacy and security minded company like @Tutanota takes the daunting arrival of quantum computing very seriously.

They're working on the first consumer post quantum encrypted cloud storage service. A timely anticipation on this development is very important since encryption (which is secure now) will be broken in a matter of seconds once quantum computers will be used for hacking. #PqEncryption #QuantumComputing

Tutanota Starts Working on Post-Quantum Secure Cloud

Tutanota aims to offer the first end-to-end encrypted cloud solution, which would be secure against quantum computers.
