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 computing ...

Quantum Technology News – Issue #8

D-wave and Google have a large announcement planned for December, as well as another D-wave purchase. Could it be an announcement of definitive data on the quantum effects within the system to put an end to the critics? Additionally, the Microsoft quantum simulator is released! Watch this space for more articles and reviews of Microsoft's Language-Integrated Quantum Operations (LIQUi|>) simulator. We are working on testing the system for some use cases and ...

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 ...

Quantum Technology News – Issue #6

As funding increases for a commercial quantum computing, breakthroughs take place faster and more publicly. The quantum computer is not a myth, but scaling and material challenges are being faced every day. Australian researchers make quantum computing breakthrough, paving way for world-first chip The new design will put quantum logic in silicon computer chips, in a major step towards the commercial manufacture of the holy grail in superfast computing. The all Silicon ...

Quantum Technology News – Issue #5

Intel joined the race for quantum computing in a big way, by investing $50 million into a collaboration with Delft University. A Yale University group published a very readable paper yesterday with a multilayer scheme for quantum circuits and proposes a top to bottom structure, as well as hits on the points of fabrication and error correction to make a scalable and fault-tolerant quantum computer. Other news includes Google and NASA Ames ...

Break RSA encryption with this one weird trick

Cryptographers HATE it! Too much math; didn’t read — Shor’s algorithm doesn’t brute force the entire key by trying factors until it finds one, but instead uses the quantum computer to find the period of a function which contains the RSA key and classically computes the greatest common divisor. RSA encryption is strong because factoring is a one-way problem. It’s very easy to multiply two primes together, but very difficult to find ...

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

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 ...

The Quantum Network Hacker Lab

TL;DR — Quantum computers are going to render a lot of current encryption techniques obsolete. Though quantum systems are inherently more secure, quantum networks and quantum key distribution suffer from some of the same vulnerabilities that classical networks do. How do we protect the quantum network? The first system has an opportunity to establish itself as a platform for quantum innovation. However, there’s also a looming question: how do we protect the quantum ...

Quantum Machine Learning — Dr. Scott Aaronson’s “Read the Fine Print”

TL;DR — The task is to figure out how to look at problems in a way that would fit them into quantum algorithms for speedup. This does not mean that this is simple at all, or possible for all problems, due to caveats that will not give the full anticipated speedup. This is the “fine print” of quantum machine learning. Recently, Dr. Scott Aaronson, a professor at MIT, published an essay about quantum ...

How secure will our data be in the post-quantum era?

It’s the end of modern cryptography as we know it, and we feel fine. Build your security for the next 50 years. If the speed of processing doubles every two years, make sure your cryptographic systems can’t be brute forced in 50 years. If you use 2048 bit RSA, it will take some quadrillion years to break it. Good enough, right? Quantum computing is about to throw that all on its head, ...
