The Green Revolution of the twentieth century increased the production of food worldwide. Hunger, in most countries, is now more a matter of economic inequality, poverty and weak governance rather …
Computer scientist Lov Grover found a quantum algorithm, or perhaps more correctly an algorithmic framework, that allows quantum computing to be applied to almost any problem. It is commonly applied …
If you have heard of quantum computers before, you have probably heard that they can factor large numbers. Factoring seems simple, if you think about small numbers: it’s easy to …
The final motivation for building quantum computers is certainly the most fundamental: sheer curiosity. Scott Aaronson, professor at the University of Texas at Austin, said in his Ph.D. thesis, back …
The number of transistors in a CPU continues to increase. Famously, the exponential pace of this growth over the last several decades is called Moore’s Law. What is the current …
Let’s begin by talking about the motivation. Why do we want to build quantum computers? The reason that’s most talked about is that quantum computers will be able to compute …
After twenty years as a subject of quiet academic research, suddenly talk about quantum computers is everywhere. You can use a quantum computer via the web, and perhaps soon buy …
