Discussing post-quantum encryption and how quantum tech will change digital security.

BB84 protocol is great in the lab, but environmental noise in commercial fibre makes it difficult to maintain a high secret key rate. Thoughts on Twin-Field QKD?
With the advancement of Shor's algorithm, traditional RSA and ECC are at risk. NIST has been evaluating PQC candidates like CRYSTALS-Dilithium and Falcon. These rely on lattice-based problems like Shortest Vector Problem (SVP): $$|| \sum a_i b_i || \le L$$ I've written a small script to verify the signature size trade-offs. Lattices are beautiful but the key sizes are massive compared to ECC. Thoughts?
