What happens to cryptography once quantum computers are everywhere? Will it still be possible to keep encrypted systems — like the Bitcoin network — secure?
This week, Google addressed the question with a blog post titled, “Experimenting with Post-Quantum Cryptography,” which looks at how possible computing speeds in the future could compromise encryption, even today.
Quantum computing, long a computer science holy grail, promises to increase processing speeds on data operations exponentially. Rather than coding data into binary bits that must be either “1” or “0,” a quantum computer would theoretically use quantum bits (“qubits”) capable of existing in… Read the rest
