Wall Street's hottest pure-play quantum computing stocks have inadvertently highlighted one of the biggest risks inherent to ...

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, ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

Beyond physics and computer science, understanding quantum computing is now essential for ethical, strategic, and creative leadership in every field.

The notion that quantum reality is your reality looms as a rich and enticing possibility. Until very recently, the very prospect was all but unthinkable, however. In everyday life there appears to be ...

“This retroactive idea. It has to be that,” says Nobel Prize-winning mathematical physicist Sir Roger Penrose, reflecting on a problem about the building blocks of reality that has dogged physics for ...

Quantum mechanics describes a microscopic world in which particles exist in a superposition of states—being in multiple ...

In 1925, German physicist Werner Heisenberg published a paper on quantum mechanics, upending classical physics and launching the world into the quantum age.

Quantum mechanics is one of the most successful theories in science — and makes much of modern life possible. Technologies ranging from computer chips to medical-imaging machines rely on the ...
