How quantum computers work: Explaining qubits to quantum superposition

Quantum computing promises to deliver processing power that surpasses current supercomputers. So far, however, they have only managed a few specialised computations.

London-based start-up Quantum Motion, has taken an approach that utilises an already well-tested and ubiquitous material: silicon to build its quantum computers. For Quantum Motion co-founder, John Morton, silicon allows fast and cheap manufacturing of quantum processors that could soon put the power of quantum computing in the palm of our hands. We visited their test facility to find out more.

How Nvidia Grew From Gaming To A.I. Giant, Now Powering ChatGPT

Thirty years ago, Taiwan immigrant Jensen Huang founded Nvidia with the dream of revolutionizing PCs and gaming with 3D graphics. In 1999, after laying off the majority of workers and nearly going bankrupt, the company succeeded when it launched what it claims as the world’s first Graphics Processing Unit (GPU). Then Jensen bet the company on something entirely different: AI. Now, that bet is paying off in a big way as Nvidia’s A100 chips quickly become the coveted training engines for ChatGPT and other generative AI. But as the chip shortage eases, other chip giants like Intel are struggling. And with all it’s chips made by TSMC in Taiwan, Nvidia remains vulnerable to mounting U.S.-China trade tensions. We went to Nvidia’s Silicon Valley, California, headquarters to talk with Huang and get a behind-the scenes-look at the chips powering gaming and the AI boom.

Is science about to end? | Sabine Hossenfelder

In his 1996 book “The End of Science”, John Horgan argued that scientists were close to answering nearly all of the big questions about our Universe. Was he right?

The theoretical physicist Sabine Hossenfelder doesn’t think so. As she points out, the Standard Model of physics, which describes the behavior of particles and their interactions, is still incomplete as it does not include gravity. What’s more, the measurement problem in quantum mechanics remains unsolved, and understanding this could lead to significant technological advancements.

Ultimately, Hossenfelder is optimistic that progress will be made in the next two decades, given the current technological advancements in quantum technologies and quantum computing.

Use of Artificial intelligence generates questions about the future of art

Artificial intelligence is everywhere and part of our conversations about education, politics and social media. It’s also a hot topic in the arts world as programs that generate art using AI are widely available to the public. But what goes into these programs, and the work that comes out, are heavily debated. Jeffrey Brown explores the influence of AI for our arts and culture series, CANVAS.

3 game theory tactics, explained

Game theory is a useful tool for decision-making in situations where the outcome depends on multiple parties. It provides a systematic way to analyze the interdependence of individuals or organizations and their potential strategies.

Not only does game theory help you identify the optimal strategy for achieving your goals, it can also help you avoid the sunk-cost fallacy — the tendency to persist in an endeavor because of the resources you’ve already invested.

By taking into account the potential actions and responses of other players, game theory allows you to minimize your losses and make informed choices that lead to better outcomes. Whether you’re negotiating a business deal or making investment decisions, game theory can be a valuable asset in helping you make smarter choices and achieve your objectives.
