Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and ...

A routine quantum optics technique just revealed an extraordinary secret: entangled light can carry incredibly complex ...

A team of theoretical researchers used thermal effective theory to demonstrate that quantum entanglement follows universal rules across all dimensions. Their study was published online on August 5, in ...

A pair of identical particles swapping places sounds like a small move. In quantum physics, it is a defining one. In everyday three-dimensional space, that swap only comes in two flavors. Either the ...

A team of physicists has uncovered a hidden topological structure within one of the most widely used sources of quantum entanglement.

In new research published in Physical Review X, scientists have designed quantum control protocols that generate processes more consistent with time flowing backward than forward. The ...

There are certain rules that the universe seems to follow in our everyday world. We can observe how objects are affected by their immediate surroundings, and we can see cause and effect in action. We ...

Princeton physicists have discovered an abrupt change in quantum behavior while experimenting with a three-atom-thin insulator that can be easily switched into a superconductor. The research promises ...
