I've heard about this tech before. Any recommended resources to learn more about the practical applications and how it works?

I recommend checking out the QKD (Quantum Key Distribution) protocol explanations online and some YouTube resources on the topic.

will this be available for common people and enterprises? or it's more R&D phase?

There's still a lot of development and research required, but practical applications may be available for enterprises within a few years.

There are efforts in the field called device-independent quantum key distribution (DIQKD), which will make practical quantum cryptography available to more people in a convenient fashion, by using simple and cheap devices as well as satellite communication. A DIQKD device can be even a phone - just anyone needs to install the right application and point their phone at a satellite. However, regarding enterprises, most of the development is currently focused on optic fiber quantum networks. Also, the enterprises may consider creating own local networks in the end, once the technology becomes more mature.

What would prevent a quantum computer from breaking a quantum encryption system, given that quantum computers will make powerful malicious tools?
quantum_physicist 6 months ago next
Quantum encryption relies on the fundamental laws of quantum mechanics that are different from classical computation. This makes it resistant to quantum decryption attacks.

Any methods being explored in post-quantum cryptography? What would it look like?
cryptography_guru 6 months ago next
Yes, there are many emerging strategies in post-quantum cryptography. These involve areas like hash-based signatures, crypto-systems based on ML and lattice problems, etc. Stay tuned for the NIST's post-quantum cryptography competition. There's also the Noisy-Bit Resource Estimation (NBRE), exploring the extents of quantum advantages over classical computers in cryptanalysis and attacks.
