Google AI Blog: Quantum Supremacy Using a Programmable Superconducting Processor

🔒 ai.googleblog.com

Quantum computing has been talked about for well over a decade, but this is the first time we are seeing something real.

We developed a new 54-qubit processor, named Sycamore”, that is comprised of fast, high-fidelity quantum logic gates, in order to perform the benchmark testing. Our machine performed the target computation in 200 seconds, and from measurements in our experiment we determined that it would take the world’s fastest supercomputer 10,000 years to produce a similar output.

10,000 years to 200 seconds? I had to do the math. That’s 1,578,000,000 times faster. What does that mean, nearly all encrypted documents we have today are probably easily decrypted with brute force tactics. Read more in this Nature article article.
