Once a baffling theory, quantum mechanics has evolved into a driving force behind modern technology and frontier research.

Quantum gravity and field theory represent a frontier where the principles of quantum mechanics are reconciled with Einstein’s description of gravity. Researchers are seeking a consistent framework ...

A team of physicists has designed quantum algorithms that can model one of the most elusive behaviors in nature: a photon ...

A Gravity Theory That Could Rewrite the Universe’s First Moments The first fraction of a second after the Big Bang has always posed a problem. Physics can describe a great deal about the universe ...

When sand grains wedge together in a funnel, the whole column locks up. Something strikingly similar can happen to quantum ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

Quantum invariants have emerged as powerful algebraic and numerical tools that encapsulate the subtleties of topological structures. By drawing on quantum group theory and the constructs of ...

The Princeton Quantum Initiative’s Ph.D. program is helping pioneer a field that promises to define the next era of discovery ...

For the last 80 years, the theory of quantum electrodynamics (QED), which describes all electromagnetic interactions, has ...

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