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, ...

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 ...

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 ...
