An international team of researchers has found a simple relationship between the rates of energy and information transmission across an interface connecting two quantum field theories. An ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

Gravity is one of four fundamental interactions. The most precise description of this force is still provided by Einstein's General Theory of Relativity, published in 1915, an entirely classical ...

A series of theoretical results from some of the field’s most prominent physicists now supports a striking idea: quantum ...

The ball rolls across the floor because it was kicked, just as Earth orbits the sun because it is tugged by gravity. The connection between cause and effect is fundamental to how we understand the ...

Quantum field theory (QFT) is a research area in theoretical physics that formulates fundamental interactions in terms of quantized fields defined over spacetime, unifying special relativity and ...

Perimeter Institute exploring interplay of quantum mechanical laws and information processing. The promise of quantum computing points to a future where highly complex problems th ...
