#1 about 2 min

Understanding Q-Day and quantum computing threats

Quantum computers pose a theoretical threat to classical cryptography systems due to exponential computation speedups.

#2 about 2 min

Getting servers ready for post-quantum cryptography today

Servers and web browsers can be upgraded today to use post-quantum algorithms like ML-KEM.

#3 about 5 min

Classical cryptography and trapdoor mathematical functions

Classical encryption relies on the specific mathematical foundations of trapdoor functions and discrete logarithms.

#4 about 9 min

Physics of quantum mechanics with superposition and entanglement

The double-slit experiment reveals how matter behaves as both measurable waves and discrete particles.

#5 about 3 min

Translating physical quantum concepts to computer science

Qubits process information using superposition probabilities and quantum logical gates to handle multiple states simultaneously.

#6 about 3 min

Breaking classical encryption using Shor's algorithm computation

Quantum parallelism and Fourier transformation allow mathematical factoring of prime numbers to bypass RSA encryption.

#7 about 6 min

Lattice-based cryptography mechanics and the ML-KEM standard

Module lattice-based cryptography relies on the difficulty of solving the closest vector problem to secure keys.

#8 about 3 min

Current readiness and modern migration security challenges

Hybrid classical-quantum encryption is progressing in browsers despite compatibility issues for distributed public key infrastructure.

#9 about 2 min

Key sizes and the classic McEliece algorithm

Post-quantum tools require network trade-offs with larger public key sizes compared to classical options.
