In classical physics, memory is defined in a straightforward way. If a system’s future behavior depends only on its current condition, it is considered memoryless. If earlier states continue to ...
A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.
An international group of researchers have investigated the role of memory in quantum systems and dynamics. Their findings ...
Physicist Paul Davies looks back at the past century of quantum mechanics—the most disruptive theory in the history of modern science.
An “echo” that arrives before you finish speaking sounds like a glitch. In quantum hardware, that kind of self-interference ...
It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is described extremely well by quantum theory, while the world of gravitation ...
To capture higher-definition and sharper images of cosmological objects, astronomers sometimes combine the data collected by several telescopes. This approach, known as long-baseline interferometry, ...
We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. This year is the International Year of Quantum Science and Technology, according to ...
The original story “ Physicists build a quantum Newton’s cradle where energy flows without resistance ” is published in The ...
Add Yahoo as a preferred source to see more of our stories on Google. This year is the International Year of Quantum Science and Technology, according to UNESCO, marking 100 years since quantum ...
In this video, we explore the concept of symmetry, regarded as the root of physics. We delve into the significance of symmetry and its connection to group theory, particularly Noether's Theorem, which ...
The original version of this story appeared in Quanta Magazine. Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time ...
