Quantum theory is often sold as a story about tiny particles, but its real disruption lands squarely on our everyday sense of what is real. At the smallest scales, the equations that power lasers, ...

Quantum theory – our best understanding of the world at the smallest level – is famously weird and notoriously confusing. It’s a theory that seems to say particles can be in two places at once, or ...

Suppose you’re a CIO or senior application planner, and you need to understand whether you should dig into quantum computing ...

Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space ...

This interaction could help explain both why quantum processes can occur within environments like the brain and why we lose ...

At first glance, some scientific research can seem, well, impractical. When physicists began exploring the strange, subatomic ...

Maria Violaris works on quantum foundations as an academic visitor at the University of Oxford, UK, and on quantum computing at Oxford Quantum Circuits, Reading, UK. Norma G. Sanchez, is the founder ...

One hundred years ago on a quiet, rocky island, German physicist Werner Heisenberg helped set in motion a series of scientific developments that would touch nearly all of physics. There, Heisenberg ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. This year is the International Year of Quantum Science and Technology, according to ...
