Schrödinger’s cat just got a little bit fatter. Physicists have created the largest ever ‘superposition’ — a quantum state in ...

Researchers from the University of Vienna and the University of Duisburg-Essen showed that metallic ...

Can a small lump of metal be in a quantum state that extends over distant locations? A research team at the University of Vienna answers this question with a resounding yes. In the journal Nature, ...

In the late 1970s, legendary physicist John Wheeler proposed a radical question: Exactly when does the universe notice that we're paying attention to a quantum experiment? And does it really matter?

Experiments reveal that metallic nanoparticles thousands of atoms wide can exist in quantum superposition, providing a ...

Physicists at the University of Stuttgart, Germany have teleported a quantum state between photons generated by two different ...

As physicists search for a theory of quantum gravity, new results show that classical gravity can still interact with quantum fields to allow matter to become entangled. When you purchase through ...

In a groundbreaking experiment, engineers at the University of Pennsylvania successfully demonstrated the possibility of transmitting quantum data over commercial fiber-optic networks using the same ...

Replication is a cornerstone of science, yet even in the natural sciences, attempts to reproduce results do not always succeed. Quantum computing promises machines that can solve certain problems far ...

Two landmark quantum experiments have sharpened one of the oldest arguments in modern physics, and the verdict is not kind to Albert Einstein’s instincts about reality. By stripping classic thought ...

Researchers from RIT’s Future Photon Initiative, in collaboration with the Air Force Research Laboratory, have produced the Department of Defense’s first-ever fully integrated quantum photonics wafer.

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and ...
