In spacetime foam, causality does not apply, because there are closed loops in spacetime where the future of an event is also ...

The Big Bang theory suggests that the universe began as a hot, dense point, expanding into the cosmos we observe today.

From slow neutrinos to quantum foam, these experiments are hoping to finally answer it What we’re still lacking, however, is a quantum field theory of gravity. Alone of the four forces ...

How did everything begin? It's a question that humans have pondered for thousands of years. Over the last century or so, ...

Quantum foam (also referred to as space time foam) is a concept in quantum mechanics devised by John Wheeler in 1955. The foam is supposed to be conceptualized as the foundation of the fabric of ...

Nobel prizewinner Alain Aspect’s ‘crackpot’ studies of quantum entanglement have explored the tricks reality plays on us — ...

Measuring disorder in the quantum realm is creating a bit of a mess. A mathematical study found that three different definitions of entropy that were previously thought to be equivalent don’t always ...

Rapid advances in applying artificial intelligence to simulations in physics and chemistry have some people questioning whether we will even need quantum computers at all.

Incoming President Donald Trump has a unique opportunity to reverse this trend and should act quickly in the first 100 days ...

This entirely diagrammatic presentation of quantum theory represents the culmination of ten years of research, uniting classical techniques in linear algebra and Hilbert spaces with cutting-edge ...

Developing many of the major, exciting, pre- and post-millennium developments from the ground up, this book is an ideal entry point for graduate students into quantum information theory. Significant ...
