In a nutshell Researchers have demonstrated mathematically that quantum systems preserve time-reversal symmetry, meaning ...

What if time is not as fixed as we thought? Imagine that instead of flowing in one direction—from past to future—time could ...

For over a century, the Maxwell’s Demon paradox has haunted physics. This thought experiment suggests that a tiny, ...

At first glance, however, quantum physics does not really seem to adhere to this rule ... but entropy can be clearly defined with mathematical equations. “Entropy is a measure of whether a system is ...

Quantum calculations amount to sophisticated estimates. But in 1931, Hans Bethe intuited precisely how a chain of particles ...

New research shows that the second law of thermodynamics, which states entropy increases over time, also applies to closed ...

Emmy Noether showed that fundamental physical laws are just a consequence of simple symmetries. A century later, her insights ...

On the heels of some big quantum computing advances in 2024, at least one company is telling businesses to get “quantum ready ...

An international collaboration sheds new light on the relationship between quantum theory and thermodynamics. The research group demonstrated that while the laws of quantum theory alone do not ...

Physicists have performed a simulation they say sheds new light on an elusive phenomenon that could determine the ultimate ...
