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?

John Martinis has already revolutionised quantum computing twice. Now, he is working on another radical rethink of the ...

A century-old thought experiment on wave–particle duality is brought into the laboratory using a single trapped atom ...

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

Record-breaking experiment shows that a cluster of thousands of atoms can act like a wave as well as a particle.

The new research demonstrates for the first time that the wave nature of matter persists even at large scales, using massive ...

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 ...

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

It has never been straightforward to probe the secrets of quantum systems. Quantum systems are powerful but extremely hard to measure. The traditional methods require astronomical resources, making ...

In 1927, Albert Einstein and Neils Bohr debated the nature of what’s known as complementarity—the idea that a photon’s dual wave-like and particle natures can’t be measured at the same time. Now, two ...

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.

Some researchers believe consciousness is a byproduct of the constantly firing web of neurons in our heads. However, others believe something more theoretical must be involved to explain our complex ...
