QUANTUM COMPUTING

SPICK LETTEL

- $IONQ -- The market leader in precision quantum computing uses ion trap technology to deliver scalable, high-precision systems. IonQ is already solving real-world problems, enabling $AMZN and $MSFT to tackle challenges in logistics, AI and materials science.

- $NVDA (+4,72 %) -- A cornerstone of quantum innovation, NVIDIA's CUDA Quantum platform enables developers to simulate quantum algorithms on GPUs, bridging the gap between quantum theory and real-world application across industries.

- $RGTI -- Rigetti focuses on superconducting qubits and aims to compete with industry leaders, but faces scalability and reliability challenges. Its Ankaa-3 system is promising, but the company needs to solve critical problems to remain competitive.

- $QBTS (+0,77 %) -- D-Wave specializes in quantum annealing and is excellent for solving optimization problems, but lacks the broader capabilities of general-purpose quantum systems. Despite decades of experience in this field, its commercial viability remains limited.

- $ARQQ -- As a leader in quantum-safe encryption, Arqit's QuantumCloud provides practical solutions to protect sensitive data from quantum-based threats, making it a cornerstone of innovation in cybersecurity.

- $GOOG (-1,83 %) -- Google Quantum AI, powered by its Willow processor, is advancing superconducting systems to achieve quantum superiority and drive breakthroughs in material simulation and AI optimization.

-$IBM (+1,55 %) -- Delivering accessible quantum systems to the enterprise through the Qiskit platform and cloud-based hardware. IBM is focused on scaling fault-tolerant systems, delivering practical tools today while working to develop cutting-edge processors such as Eagle and Condor.

- $HON (-0,22 %) -- Utilizing Trapped Ion technology, Honeywell delivers unmatched precision for real-world applications in aerospace and logistics. The partnership with Cambridge Quantum positions the company as a leading provider of quantum solutions for the enterprise.

Quantum computing stocks are bullshit.

Tell me, aren't the crypo people shitting themselves over this? I once heard somewhere that this solves crypto encryption in no time. And then the whole crypto thing is worthless?

And yes, I haven't "studied" coins, I'm old.... Blablablablubbbb.....

- Theoretically:
Yes, a powerful quantum computer could "decode" Bitcoin by deriving private keys from public keys (Shor algorithm). However, the impact on mining (SHA-256) is less dramatic (Grover algorithm).

- Practical:
Currently and in the near future, quantum computers are not able to crack Bitcoin, as the technology is not yet advanced enough.

- Long term:
The Bitcoin community will likely take steps to secure Bitcoin against quantum computers before they pose a real threat.

It's all still in the very distant future ⚡️

@Cro ah ok, so there are still ways to take countermeasures. That's news to me. Ok, thank you 🙏

@Nobody_123 one of the best measures is to have your bitcoins and cryptocurrencies on your private cold wallet 😉.

One countermeasure would be to improve the address formats and then send all coins to new addresses.

I think it would be great if lost coins could be put back into circulation. There is no rational advantage, but I find the idea somewhat relieving.

@Cro but (in case I have understood correctly), only your key should be stored in the wallet and the coins are permanent and only on the network. So your argument is useless, because with these PCs everything is simply pooped up and taken away within a very short time? Or am I seeing and understanding it wrong?

@Nobody_123 Your assumption is correct. It would theoretically be possible to obtain the keys. However, this becomes more difficult the more up-to-date the address formats are. It is therefore reasonable to assume that the oldest keys/addresses (some of which have been inactive for 10 years) will be cracked first, but everyone else could update or switch to better ones by then.

@Peter69 I understand what you're writing, but I can't quite understand your argument.

But anyway, the more I think about this topic, securing crypto seems to me to be the least of the problems.

@Peter69 But shouldn't that have a negative impact on the price when the "dead" coins are back in circulation? Supply and demand and all that?

It may well be that such an announcement could trigger a subsequent buying opportunity ;)

Cryptocurrencies are the last thing I'm worried about. It's a different story when it comes to the security of critical infrastructure - finance, energy supply, communications and government systems. These are indeed at risk.

Thanks for this helpful overview.
As far as I understand, quantum computing is not really commercialized yet. There is a lot of research going on and recently companies like Google and also IBM have made progress, especially in terms of instability and noise which is still the biggest problem. So we are only at the very beginning of the movement. Nevertheless, there will continue to be a lot of research, investment and it will come. How fast is everyone's guess probably at least 10 years.
