In quantum physics, objects can exist in multiple states at the same time—a phenomenon known as quantum superposition, where ...

Physicists at Kyushu University in Japan have outlined a technique that could bring one of the most elusive goals in modern ...

A key question in physics is whether gravity follows quantum rules, but testing this is difficult because gravitational ...

A cloud of helium atoms split, scattered and fell under gravity, yet still behaved as if its parts were linked. That is the ...

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 ...

Recent theoretical and experimental endeavours in quantum gravity have increasingly focused on the interplay between gravitational interactions and quantum entanglement. This research seeks to ...

For the first time, scientists have observed quantum entanglement in the momentum of massive particles. The result, decades ...

A new experiment using Google’s Sycamore quantum processor has taken a bold step toward testing ideas from quantum gravity. For the first time, researchers successfully sent quantum information ...

In quantum mechanics, position and momentum cannot be simultaneously determined with arbitrary precision. Conventionally, position uncertainty is reduced to improve estimation accuracy. In this work, ...

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 ...

Quantum physicists observed atoms entangled in motion for the first time, using helium atoms with mass and gravity, opening new ways to explore how quantum mechanics interacts with gravity.

Quantum physicists at the Australian National University (ANU) have achieved a major milestone by directly observing atoms ...
