Top 3 Quantum Myths and Misconceptions

Quantum mechanics is hard. No one is debating that. But there are a lot of bad facts out there just because the metaphors used were not explained well. Let's debunk myths and explain some misconceptions. “QUANTUM COMPUTERS ARE USEFUL BECAUSE THEY CAN CHECK ALL POSSIBILITIES AT ONCE” No. That’s not how that works. Where did this explanation come from? More than fifty quantum algorithms have been discovered. Each quantum algorithm works differently, but ...

Why the NSA moving away from Suite B cryptography due to quantum computers makes total sense

TL;DR —Quantum computers could actually have been the trigger to begin the move to post-quantum cryptography.  Even though the Snowden files released in 2013 showed limited progress from the NSA on quantum computers, the last 2 years since have been a storm of real, practical results, as well as funding poured into both companies and academic research. One of the comments I most often hear is “Well, Snowden released documents in 2013 showing ...

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 #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 New design will put quantum logic in silicon computer chips, in a major step towards commercial manufacture of holy grail in superfast computing. The all Silicon chip means that ...

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 ...

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 compute 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 prime factors ...

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 ...

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 ...
