Artificial intelligence is still remaking the global economy, but a second, deeper tremor is already building underneath it.

Quantum technologies are highly promising devices that process, transfer or store information leveraging quantum mechanical ...

Researchers have designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path ...

Two landmark quantum experiments have sharpened one of the oldest arguments in modern physics, and the verdict is not kind to ...

What if the flow of time isn’t as one-way as it seems? Researchers from the University of Surrey have uncovered evidence that in the strange world of quantum physics, time could theoretically run both ...

Although the basic idea of quantum physics dates back to the earliest years of the twentieth century, it wasn’t until 1925, on the German island of Heligoland, that Werner Heisenberg had the ...

Long considered a serious technical challenge, superradiance could actually help quantum devices go even further.

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.

A rift runs deep through the heart of physics. The general theory of relativity, which describes gravity, clashes with quantum physics. In an effort to seal that physics fissure, untold numbers of ...

A quantum computer has reached new heights. The first quantum computer in space is now orbiting Earth on a satellite, scientists report. Launched on June 23, the computer had to be designed to fit in ...
