"God does not play dice." This famous remark by Albert Einstein critiqued the probabilistic nature of quantum mechanics.

The interplay between quantum theory and gravity is one of the most challenging problems in physics today. Using new groundbreaking approach, researchers hope that quantum networks will help them test ...

Leader and Physics Quantum theory at 100: Let’s celebrate its power and provocation Quantum theory started with a bout of hay fever, and went on to transform our view of the universe – but its ...

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.

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has ...

A century since Werner Heisenberg changed the course of physics, five of the world's leading physicists examine the greatest achievements of quantum mechanics and look forward to the next 100 ...
