A new experiment involving a network of entangled atomic clocks could finally help us test how quantum mechanics fits with ...

Scientists propose using quantum-entangled clocks to test how gravity affects quantum mechanics in curved spacetime.

In quantum mechanics, time is an external and unchanging parameter. It does not exist within the quantum system itself but is instead measured through interactions with external entities.

A test using atomic clocks will watch superpositions ride Earth’s curved space-time and see if Einstein can play nice with ...

Speculative elements may not be necessary to explain the cosmos. A team of researchers, led by Raúl Jiménez, an ICREA ...

Quantum networking is being rapidly developed world-wide. It is a key quantum technology that will enable a global quantum ...

Input/output is the term for time before and after a particular physical moment or scenario, and in certain quantum scenarios, those ‘befores’ and ‘afters’ can be interchangeable.

There, Heisenberg developed the framework of quantum mechanics. At the time, quantum theory was just a loose collection of ideas about the quirks of physics on the scale of atoms.
