What’s the difference between quantum annealing and universal gate quantum computers?

Just as a GPU processes instructions related to graphics exponentially faster than a CPU, certain problems can be solved quadratically or polynomially faster with quantum algorithms, by exploiting the quantum effects of superposition and entanglement. But what is quantum annealing, and how does it differ from a universal gate quantum computer? D-Wave, the most famous quantum annealer, and universal gate quantum computing are not competitors. While they rely on the same concepts, ...

Quantum Technology News – Issue #10

A lot of companies are finally giving concrete timelines to the "first" quantum computer. IBM's insights show that the first quantum computer will exist in less than 10 years (2025 estimate). Therefore, applications of all aspects of quantum communication and quantum computing have jumped, with many companies setting up research facilities and thinktanks within industry and academia to explore the applications quantum computing may have upon their industry, like Airbus, below. Additionally, ...

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

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 ...

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 ...

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 ...
