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

Physicists have long suspected that gravity might have a hidden quantum side, but for decades the idea has been more mathematics than measurement. A new proposal for a tabletop experiment now suggests ...

Physicists have pushed one of the strangest ideas in science into new territory, holding tiny clumps of metal in a quantum limbo that recalls Schrödinger’s famous cat. Instead of a single atom or ...

Let’s talk about quantum gravity experiments that can be done here on Earth! If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple ...

Killing horizon: a thought experiment suggests that the presence of a black hole can decohere a quantum superposition. (Courtesy: Shutterstock/Rost9) A new thought experiment suggests that the mere ...

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, ...

Even if you are not a quantum physicist, you will most likely have heard of Schrödinger’s famous cat. Erwin Schrödinger came up with the feline that can be alive and dead at the same time in a thought ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...
