Quantum key distribution vs post-quantum cryptography: what each protects against
How quantum key distribution and post-quantum cryptography differ in goals, assumptions, deployment trade-offs, and the threats each addresses.
Quantum error correction and logical qubits, explained
How quantum error correction turns many noisy physical qubits into more reliable logical qubits, and why code distance, thresholds, and surface codes matter.
