An Introduction to Quantum Computing - DZone AI

#artificialintelligence

There is a lot of buzz about quantum computing, and Microsoft has officially announced a Quantum Development Kit and Q#, the language for quantum computing. In this article, I am going to cover some of the basics of quantum computing and also set up an environment on our local machine with Visual Studio 2017 to get started with quantum programming. Quantum theory is the branch of physics that deals with the world of atoms and the smaller subatomic particles inside them. The laws of physics are different at the atomic level and the classic laws of physics that we can observe in our daily life won't apply here. Classic computers (the machines we use in our daily lives, including laptops, desktop, servers, etc.) have made our life very simple and fast.



How toy street lamps are shedding new light on quantum computing

PCWorld

If you've ever had a train set, you might remember the tiny street lamps that are often part of the model landscape. Today, the bulbs from those toy lamps are helping to shed light on quantum computing. In fact, there's been a spate of developments lately in quantum computing, and not just IBM's announcement of its upcoming cloud service. Here are three recent advances from research institutions around the world. Quantum computers are eagerly anticipated for the huge gains they promise in efficiency and performance.

It's only a matter of time before quantum computers start solving real-world problems

#artificialintelligence

No, quantum computing did not come of age with Google's Sycamore, a 53-qubit computer solving in 200 seconds a problem that would take even a supercomputer 10,000 years. Instead, it is the first step, showing that a functional computation can be done with a quantum computer, and it does indeed solve a special class of problems much faster than conventional computers. This is not that quantum computers have now superseded classical computers. The hype of quantum supremacy is misleading as it is based on a very narrow definition quantum supremacy; quantum supremacy is one quantum computer beating all classical computers for one specially constructed task. The bad news -- for the science fiction enthusiasts -- is that it is not going to replace our current computers but will be useful only for a special class of problems.
