Post-Quantum Cryptography at Google

Google, one of the front runners in the race for quantum computing, announced their first experiments with post-quantum cryptography. Why does it matter? If Google is starting to worry about post-quantum cryptography, maybe they had a breakthrough in large scale universal quantum computing? See the original blog post here: https://security.googleblog.com/2016/07/experimenting-with-post-quantum.html Google’s Post-quantum cryptography experiment It’s time to explore options for quantum safe algorithms beyond theoretical implementations. Google has launched “CECPQ1” - a post-quantum key exchange ...

Quantum Technology News – Issue #9

The biggest news of the week is the long anticipated Google quantum computing announcement. The announcement states that the D-Wave machine is more than 10^8 times faster than simulated annealing running on a single core. Independent analyses by Dr. Scott Aaronson show that while the results are showing that D-Wave is becoming more mature and probably has quantum effects, the technology suffers the drawbacks of just being built on old quantum ...

Quantum Technology News – Issue #7

The most exciting thing about these last few weeks is that companies and governments have actually started putting timelines on when you will be able to have the first quantum computers. Large companies have publicly come out and said that in 10 years, we will have quantum computing. Some governments are hush-hush, but others are putting a 2-3 year timeline, while other companies are saying 5-7 years. Whatever the timeline ...

Why don’t post-quantum encryption standards exist yet?

TL;DR — With increased funding, quantum computing is moving into a “Manhattan Project” era, where the timeline to a small, useable quantum computer could be drastically reduced. When the first quantum computers are ready to go in the next 5–10 years, we need to have security protocols in place. Post-quantum cryptography solutions do currently exist. We still have time, but we need to take the threat seriously. Establishing global post-quantum security standards Small, useable quantum computers ...
