For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...

Even given a set of possible quantum states for our cosmos, it's impossible for us to determine which one of them is correct ...

To most of us, time feels as solid as the phone alarm that drags us out of bed or the calendar that fills up faster than we ...

In an effort to bring together the domains of gravity and quantum theory, Albert Einstein and Nathan Rosen proposed a ...

Researchers have demonstrated that quantum entanglement can link atoms across space to improve measurement accuracy. By ...

Entangled atoms, separated in space, are giving scientists a powerful new way to measure the world with stunning precision.

A NOON state is a superposed quantum state where N particles are in one state "at the same time" and in another "at the same time". Here, the particles are trapped in two wells, within a trap formed ...

Thermodynamics and statistical physics provide a unified framework linking the macroscopic laws of energy, work, and entropy to the microscopic motions of particles. Thermodynamics, rooted in the laws ...

Until now, creating quantum superpositions of ultra-cold atoms has been a real headache, too slow to be realistic in the laboratory. Researchers at the University of Liège have now developed an ...
