Hello, cryptonians! 💻💡
Recently, a scientific study on quantum computing stirred the world again. The media talked about the impending doom for cryptography, and your personal wallet becoming an open book. But is it really that scary? Let's find out!

What happened? 🔍
Scientists have conducted an attack on symmetric ciphers using a real quantum computer for the first time. Yes, that sounds impressive. But here are the key details that are often forgotten:
The attack was conducted on 22-bit keys. That's only 4,194,304 combinations — laughable numbers compared to the 2048- or 4096-bit keys used today.
The results of the research resemble a proof of concept rather than a real threat.

What do experts say? 👨🔬
According to Avesta Khojati from DigiCert:
> "This is an intriguing study, but it will not cause a quantum apocalypse right now."
Let's be honest: the research is useful; it shows how quantum computers can threaten weak ciphers. But it does not pose any threat to current standards such as AES-256.

Why do you not have to worry for now? 🛡️
1️⃣ The power of quantum computers is still insufficient. Modern quantum machines are simply not capable of attacking complex ciphers with long keys.
2️⃣ Classical cryptography technologies remain strong. AES-256, which protects your data, remains virtually unbreakable. Even if quantum computing becomes more powerful, developing a real threat could take decades.
3️⃣ Development of post-quantum cryptography. Scientists are already working on standards that can withstand quantum attacks.

So why did the media inflate the panic? 📢
Hype always attracts attention, especially when it comes to complex and frightening technologies. But it's important to understand that headlines like "Quantum computers threaten all the data in the world" are, to put it mildly, an exaggeration. 🙃

What can be done already? 💡
Use modern ciphers such as AES-256.
Keep an eye on developments in post-quantum cryptography.
Remember, panic is not a solution, and a sober approach always prevails.

Conclusion: there will be no apocalypse 🚀
Yes, quantum computers are impressive and promising. But your wallet, personal data, and bank accounts are currently completely safe.
