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 ...

An international group of researchers have investigated the role of memory in quantum systems and dynamics. Their findings ...

The original story “ Physicists build a quantum Newton’s cradle where energy flows without resistance ” is published in The ...

A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

An international team of scientists from IBM, The University of Manchester, Oxford University, ETH Zurich, EPFL and the University of Regensburg have created and characterized a molecule unlike any ...

Light does not “think” in any human sense. Still, under the right conditions, it can behave in a way that looks uncannily like a memory system.

Physicist Paul Davies looks back at the past century of quantum mechanics—the most disruptive theory in the history of modern science.

Experts are calling for the cryptographic systems on which the entire network depends to be made ready now for the imminent ...

Forgetting feels like a failure of attention, but physics treats it as a fundamental process with a measurable price. At the smallest scales, erasing information is not free, it consumes energy and ...

Sometimes a visually compelling metaphor is all you need to get an otherwise complicated idea across. In the summer of 2001, a Tulane physics professor named John P.

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 ...

Shaped by a different biology or culture, other intelligent civilisations – if they’re out there – might understand the ...
