The entangled clocks can test how quantum theory behaves in the presence of curved space-time as predicted by Einstein, or whether our current theories break down. Hoboken, N.J., July 14, 2025 — ...

Quantum networking is being rapidly developed world-wide. It is a key quantum technology that will enable a global quantum internet: the ability to deploy secure communication at scale, and to connect ...

Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama themselves. A new theoretical framework now flips that script, treating space ...

Nothing is complicated because in physics even completely empty space is described as being full of quantum fields doing complicated things even when nothing else is there. One prediction that’s been ...

Researchers say they may have taken a significant step toward explaining the origin of gravity. SHARJAH, EMIRATE OF ...

In a pioneering twist on quantum networking, physicists have proposed using entangled atomic clocks to probe how gravity’s bending of space-time affects the quantum world. The work—led by researchers ...

Do I need a spaceship to go to the outside of the universe?Recently, I have been researching various aspects of quantum ...

Quantum Information Dynamics in Curved Spacetime investigates how gravitational fields and the geometry of spacetime influence quantum information processes. Employing quantum field theory in curved ...

A team of researchers led by the University of Warwick has developed the first unified framework for detecting "spacetime fluctuations"—tiny, random distortions in the fabric of spacetime that appear ...

A proposed experiment could shed light on the unknown interplay of quantum theory and general relativity. Quantum theory in curved spacetime can be theoretically understood beyond the limit at which ...

Diagrammatic representation of the entropic quantum gravity action. The action for gravity is given by the quantum relative entropy between the metric of the manifold and the metric induced by the ...
