Quantum mechanics and general relativity are the two pinnacles of 20th-century physics. In their respective fields, scientists have demonstrated time and time again how correct these theories are.

The exploration of quantum information challenges objective reality, positing the universe as a hologram is explored through ...

This week’s cover of Science features a graphic symbolizing the Greek letter Ψ (psi), which represents the wave function, a ...

The famous double-slit experiment brings into question the very nature of matter. Its cousin, the quantum eraser experiment, ...

For a future quantum internet to work, scientists need to perfect a quantum repeater that can send information over long ...

Scientists are using anesthesia to probe the quantum roots of consciousness—and the research offers tantalizing evidence.

The mysterious quantum universe questions our conventional understanding of reality. In this reality, particles can exist in several states at once, be entangled across great distances, and where the ...

Nearly 50 years ago, physicists floated a bold idea: our universe might be stuck in a false vacuum. This state feels stable, but deep down, it's not. Over enormous timescales, it could suddenly tip ...

Recent progress in both analog and digital quantum simulations heralds a future in which quantum computers could simulate — and thereby illuminate — physical phenomena that are far too complex for ...

Before Einstein, before Bohr, there was a Jesuit priest with a telescope and a startlingly modern vision of the universe.

On the centennial of modern quantum mechanics, the Nobel Committee awarded the year’s most prestigious physics prize to an experiment that demonstrated how quantum effects play out on large ...

Everyone's racing to build the most powerful quantum computer. But what if the winner is the one that plays nicest with ...
