Jiuzhang 3.0 is not a cryptographic threat. But the next generation of universal fault-tolerant machines will be!
Recently, China made waves with its photonic quantum computer, Jiuzhang 3.0, solving Gaussian boson sampling problems 10 billion times faster than classical supercomputers.
✅ Yes, it's a leap in quantum speed.
❌ No, it cannot break encryption - yet.
Jiuzhang isn’t a universal quantum computer.
❌ It can’t run Shor’s algorithm.
❌ It has no error-corrected qubits, no gates, and no fault tolerance.
But the writing is on the wall.
🧠 What would it take to break RSA-2048?
- 4,000 logical qubits
- Millions of physical qubits (with error correction)
- A week of compute time, maybe less
And it’s no longer theoretical - it’s on the roadmap
⚠️ The risk isn’t Jiuzhang. It’s complacency.
Most organizations are still relying on RSA and ECC, while quantum research accelerates at a pace few outside the field are tracking.
Harvest-now-decrypt-later isn’t a theory anymore.
Data stolen today could be decrypted in the next decade - or sooner.
🛡️ The move to post-quantum cryptography isn’t optional.
It’s the bare minimum for long-term security.
If you’re not planning for a post-quantum world, someone else is - and it won’t be for your benefit.

This Is Just a Test Post. DO NOT READ
Maybe Some Elite Players Will Understand the Meaning
Sometimes, the most significant messages hide behind the simplest words.
This post? Just a test. Or so it seems.
Most will scroll past without a second thought. But a few—those with sharp eyes and sharper instincts—might catch the deeper layer. It’s not obvious. It’s not loud. But it’s there.
And here’s the kicker:
If this lands the way it’s meant to, it could cost Facebook millions.
No clickbait. No exaggeration. Just quiet potential in plain sight.
Maybe nothing happens. Or maybe, everything shifts.
That part? Depends on who’s watching.
You know who you are.

🔐 Encryption ≠ Security
🕒 Last month, our team took on a challenge called crypto-numerology.
At first glance, it looked solid: a stream cipher modeled after ChaCha20. It had proper constants, key/nonce structure, and ciphertext that looked convincingly random.
But there was one critical detail.
👉 It only used one round of mixing.
That one shortcut changed everything.
With a known key and a few plaintext/ciphertext pairs, we could fully recover keystream blocks. From there, it only took a small brute-force over a 32-bit counter to reveal the flag.
🔍 What struck me most was how realistic this failure felt.
“One round should be fine.”“Nobody will reuse this nonce.”“It’s just for internal use.”
Security doesn't usually break in dramatic ways - it rots quietly, through shortcuts and assumptions that go unchallenged until it’s too late.
