In the everyday world that humans experience, objects behave in a predictable way, explained by classical physics. One of the ...

But researchers still disagree widely on how best to describe the physical reality that lies behind the mathematics, as a ...

Quantum mechanics remains mysterious as it turns 100, and a landmark survey reveals physicists are still sharply divided over its meaning.

Some physicists think our reality is a kind of cosmic hologram, with space, time, and gravity as manifestations of a ...

Nature survey shows that disagreement about the meaning of quantum physics remains strong, even 100 years in. And that’s OK.

In 1905, Einstein established relativity under the condition of denying the absolute space-time valid in Newtonian mechanics. In those days, the quantum theory was also established by accepting De ...

Scientists propose a groundbreaking experiment using quantum computers and atomic clocks to test whether gravity alters the ...

When a German physicist returned from a health retreat 100 years ago, his ideas sparked a debate about reality, and gave rise ...

The correlation of particles separated by distance so that what happens in one affects the other. For decades, quantum entanglement has been a major topic in quantum mechanics and has been a point ...

Qubits have special properties that allow them to exist in multiple states simultaneously — a phenomenon called superposition ...

Quantum computing is a revolutionary form of computing that uses the principles of quantum mechanics to perform calculations that would be infeasible or impossible for classical computers.
