Breaking encryption with 100x less qubits? #quantumcomputing #encryption #security

Quantum, we’re so back in 2023. This is theory, but it’s exciting for these reasons ⬇

The model has promising results, reducing the estimated numbers to elliptic curve discrete logarithm computation can be achieved with 126,000 cat qubits in 9 hours and 350,000 cat qubits in 4 days. This is still beyond our current capabilities! The model is also assumes a lot underlining hardware assumptions and quality. There was assumed infinite memory lifetime, and certain levels of physical noise, logical error rate. As I say, we need to build the machines! But in the end, the scientists in quantum computing, in theory and experiment, are pretty intrigued by the result. These are not WILD estimates, just we aren’t there yet.

And scientists and engineers are working on both sides of the problem. Hardware scaling and qubit fidelity, as well as the error correction and algorithmic ends. At some point, they will meet in the middle!

BTQ’s QByte Quantum Risk Calculator tracks qubit counts and quantum infidelity, too, if you want to check on progress on the hardware end.

Alice & Bob, a collaborator on the paper, wrote a blog post about the results, which I recommend reading. But I like the summary in the end on impact:

“For this reason, I believe the obtained numbers should not be interpreted as the ultimate goal of the hardware effort but rather, illustrate how concatenated cat codes may reduce drastically the engineering challenge.”

After some dead time in quantum, a lot of new results are coming.

Thank you for this wonderful insight! Your videos are informative and easy to understand. I'm looking forward to more content like this! 👍🏻

Thank you for the update! I love to see you back! I'm switching to ADA now :D

Waiting for the Quantum hype within the next couple of years. When it comes to the cryptocurrencies the first quantum resistant blockchain mainnet of Qanplatform will be launched in 2024.

I need your help for my carrer choice.
I actually have done my bachelors in commerce but in real from last 3 years I am doing researches and learninh about Space science and Quantum Physics as by my own through online sources.

And I know I born for it.
I am really confused how Can I proceed myself to Quantum computing job. I have really in dept knowledge of it but as i Know the world will always see my graduation degree which is in commerce.

I planned to do masters in data science + some quantum computing online courses so I can divert myself easily to this technical field.
Kindly suggest me what you think will be a better road map for me. You are genius after watching you I just motivated again to not giving up from my dream and goal.

hello Ma'am I am a science student from India ..I'm interested in Qauntum Physics

Woow is the 100x acceleration factor given for a specific key size or is it for any key size ? Because in the 2nd cas we could maybe patch with keys larger (e.g. adding 2 low case letters multiplys by 26x26=676 the possibilities)

Well what I know about the quantum computer is how it looks like, is it made of gold or copper?

Is that cracking via Shor's algorithm? So the vulnerability will be with wallets that have exposed public keys (signatures) from spends? I doubt they can reverse the hash for the address of an unspent wallet. If everyone only used BIP-44 or BIP-48 HD wallets then there wouldn't be any problems.

Which quantum vulnerable algorithm is better then? RSA?

[premaryan]

Can u pls bring a course for high school student who r interested in computer computing can have some basic ideas abt all of this thing ?. Mam please 🥺❤

[dgpreston]

So, me and my laptop have been beaten? Pfft!!!
😮😢😂😅😊

[darthinvader]

too late for this, people are already on lattice cryptography

[pebcak]

It'll be okay, just buy QRL and sleep like a baby knowing QC wont be breaking OTS XMSS or lattice signatures any time soon. Quantum Resistant Ledger has got your back.
