What is a Quantum Computer?

The planet is in trouble; fossil fuels are being depleted and are contributing to global warming. Plants, however, have been directly harnessing solar energy for as long as they have existed. A flash talk from Tomas Leijtens. 

Kathryn boast gives a flash talk discussing what we already know about dark matter, and what we still have to find out about it. There is quite a lot of conclusive evidence for the existence of dark matter, but we still have very little idea of what it actually is. Kathryn Boast ... Show More

Albert Einstein is one of the greatest scientists to ever live, and even he made mistakes, as Luke Jew explains - A comforting thought for all of us! This great mistake was about the astrophysics that will ultimately determine how our universe will end. 

Every year, new computers are being developed that are faster and smarter than ever before. But if you really want to take things to the next level, you've got to go quantum. CrowdScience listener Atikah in Hungary likes the sound of a quantum computer but wants to know: what exa ... Show More

We travel to a facility in the south of England to see one of the super-fast computers in action.We’ll find out what quantum computing has the potential to do, what its going to take to make that a reality and importantly whether quantum businesses are making any money...Presente ... Show More

A quantum computer isn't just a more powerful version of the computers we use today; it's something else entirely, based on emerging scientific understanding -- and more than a bit of uncertainty. Enter the quantum wonderland with TED Fellow Shohini Ghose and learn how this techn ... Show More

What's quantum computing? It's not just for scientists anymore! Discover how this mind-bending tech could change everything from medicine to cybersecurity. Find the full article and more on https://englishpluspodcast.com/quantum-computing-unlocking-the-future-of-tech-and-your-wor ... Show More

Dr Scott Aaronson (MIT, UT Austin) gives the 2016 Strachey lecture. In the near future, it will likely become possible to perform special-purpose quantum computations that, while not immediately useful for anything, are plausibly hard to simulate using a classical computer. These ... Show More

Quantum computers could transform our lives. Based on a branch of Physics that even Einstein found "spooky", the machines are still in their infancy. But governments and corporations are spending billions trying to turn them into workable technology. Neal Razzell finds out why by ... Show More

Here we set the scene for an explanation of the functioning of quantum computers and their significance. What are the problems that quantum computation might solve? What is the fundamental advantage of computation and hence quantum computation for humanity and for an understandin ... Show More

While quantum computers show great promise for the future, today’s processors are small and noisy – and this makes it very difficult to do meaningful quantum calculations right now. To address this problem, researchers are developing clever quantum algorithms that make the most o ... Show More

This month’s episode of the Physics World Stories podcast looks in depth at the science behind the 2022 Nobel Prize for Physics and the technologies that are emerging as a result. Alain Aspect, John Clauser and Anton Zeilinger shared this year’s award “for their experiments with ... Show More

What if microparticles could help us solve the world's biggest problems in a matter of minutes? That's the promise -- and magic -- of quantum computers, says Matt Langione. Speaking next to IBM's quantum computer, he explains how these machines solve complex challenges like devel ... Show More
