A century-old thought experiment on wave–particle duality is brought into the laboratory using a single trapped atom ...

In the late 1970s, legendary physicist John Wheeler proposed a radical question: Exactly when does the universe notice that we're paying attention to a quantum experiment? And does it really matter?

Physicists have coaxed clusters of thousands of atoms into a delicate quantum limbo, creating a record breaking version of ...

A groundbreaking experiment demonstrates yet again that light exists both as a wave and a particle in the quantum world—but we can’t see both at the same time. Reading time 3 minutes Albert Einstein ...

Does quantum physics place limits on the extent to which we have free will? This long-debated question stems from the way different physicists interpret the mathematics of quantum theory, but now ...

In the everyday world that humans experience, objects behave in a predictable way, explained by classical physics. One of the important aspects of classical physics is that nothing, not even ...

Over the years, data centers have reinvented themselves through virtualization, the cloud and AI. The next iteration is ...

A new discovery suggests gravitational fields can enable matter to become quantum entangled — and that's even if the concept of quantum gravity does not exist. The idea comes from two London-based ...

As physicists search for a theory of quantum gravity, new results show that classical gravity can still interact with quantum fields to allow matter to become entangled. When you purchase through ...
