Time travel has long been a staple of science fiction, captivating imaginations with the possibility of moving through time as easily as we travel through space. However, the question remains: how ...

A real mind-melter: Quantum mechanics is strange, but even for a field of science that regularly defies our conventional understanding of reality, the latest discovery is particularly baffling.

The world’s best clocks may be sensitive to an odd mix of quantum and relativistic effects that would stretch time and test ...

A glittering hunk of crystal gets its iridescence from a highly regular atomic structure. Frank Wilczek, the 2012 Nobel ...

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 ...

What if the flow of time isn’t as one-way as it seems? Researchers from the University of Surrey have uncovered evidence that in the strange world of quantum physics, time could theoretically run both ...

For decades, quantum physics and general relativity have stood as two powerful but separate theories. Quantum physics explains the behavior of tiny particles like atoms and photons. General relativity ...

Allison Kealy is affiliated with Quantum Australia as a board member. Allison Kealy is a research collaborator with RMIT University and Phasor Quantum. Quantum technology is no longer confined to the ...

Although the basic idea of quantum physics dates back to the earliest years of the twentieth century, it wasn’t until 1925, on the German island of Heligoland, that Werner Heisenberg had the ...
