In recent times researchers have discovered a formula to understand where quantum objects when they are transmitted. With this formula researchers may be able to have better control over quantum computing. This formula was discovered at Yale and helpt to control open quantum systems in many different situations. The researchers can control quantum objects with the model of rain and a gutter. The gutter and the gates within the gutter are meant to represent dissiapation. Usually quantum objects get destroyed in this process, as they are too fragile, but ocassionally the objects can be desgned to be robust enough to control and protect agaisnt this. The formula the researchers created showed that there is a situation where one superposition is not possible. Professor Amber Jiang describes it as "
In other words, such a superposition state always loses some of its quantum properties as the 'droplet' flows completely into both puddles."
I found this aritcle interesting as I think that it is important that we understand what we are working with. In this case I think finding a deeper understanding of quantum objects is important if researchers intend to keep exploring the world of quantum computing. I also thought it was cool how the researchers compared their formual to an understandable model. I think that it is very helpful to undertanding computer science when the idea is compared to a real life scenario.

Quantum computing and the term "quantum" in general have always been topics in both physics and computer science that are abstract and not very straightforward. Not much is understood about quantum objects and it continues to be a topic of interest in the world of science. I like this article because it sheds light on the research that is happening that many people don't know about, and the fact that everyday that passes we are making greater strides towards quantum computing and generating data at unimaginable speeds.
ReplyDeleteI think this is very cool. I never understood how quantum computing would make use of the multiple states one of these computer's registers can be in if we can't measure it. (or so I thought) The fact researchers are understanding these concepts and gaining more use from them is fascinating and it'd be really cool to see where it takes us.
ReplyDeleteRegardless, this shows how even he most unimaginably distant things can have use in the building of computers. Most people think engineering, physics, math are needed, but *quantum* physics and the higher-level math that goes with it is and interesting subject that's been applied to computers over the few past years.
