The simulation of strongly interacting many-body systems is a key objective of quantum physics research, as it can help to ...

Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in ...

Scientists have been using complicated, hypothetical particles to explain the Big Bang, but this theory posits that a simpler ...

Quantum theory describes events that take place on extremely short time scales. In the past, such events were regarded as 'momentary' or 'instantaneous': An electron orbits the nucleus of an atom—in ...

Quantum field theory (QFT) is a physics framework that describes how particles and forces behave based on principles rooted in quantum mechanics and Albert Einstein's special relativity theory. This ...

In the strange world of quantum mechanics, objects can exist in several states at once. This concept, called superposition, is one of the most puzzling features of quantum theory. A particle, for ...

The measurement problem in quantum mechanics looks at how an experimental outcome changes, simply by observing it.

The original version of this story appeared in Quanta Magazine. Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time ...

The problem with quantum mechanics, or at least the reason even physicists don’t understand it, isn’t that it paints an unfamiliar picture of reality. It isn’t difficult to accept that the world of ...
