What if the universe remembers? A bold new framework proposes that spacetime acts as a quantum memory. For over a hundred years, physics has rested on two foundational theories. Einstein’s general relativity describes gravity as the curvature of space and time,

Scientists then defined the “edge” of this gaseous material by introducing a laser, which formed a wall around the atoms. Once atoms encountered this light, they flowed in just one direction—much like electrons at ultra-small quantum scales.

In 1964, physicist John Bell formulated what became known as Bell's Theorem, showing that if quantum mechanics is correct, such correlations cannot be explained by any hidden loca

A quantum computer has reached new heights. The first quantum computer in space is now orbiting Earth on a satellite, scientists report. Launched on June 23, the computer had to be designed to fit in a small package, use limited power and endure wild ...

Scientists using Google’s quantum processor have taken a major step toward unraveling the deepest mysteries of the universe. By simulating fundamental interactions described by gauge theories, the team showed how particles and the invisible “strings ...

"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in physics." The first step toward quantum gravity, the "holy grail of physics," may be hiding in a quantum recipe to cook up black holes.

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger Penrose, when matter collapses under its own gravitational pull, the result is a “singularity” – a point of infinite density ...

Researchers have experimentally demonstrated a quantum tornado. Electrons form vortices in the momentum space of the quantum semi-metal tantalum arsenide. A team of researchers from Würzburg has for the first time experimentally demonstrated a quantum ...

Today's encryption works well, until tomorrow's quantum computers arrive. This article was originally published at The Conversation. The publication contributed the article to Space.com's Expert Voices: Op-Ed & Insights. We have developed a new way to ...

Quantum mechanics remains a cornerstone of modern physics, providing a framework for understanding phenomena at the microscopic scale. At the heart of its formulation lies the concept of Hilbert spaces—a complete vector space endowed with an inner ...
