Can quantum systems become more disordered, as thermodynamics would predict? Yes, they can - if a proper definition of "entropy" is used. It is one of the most important laws of nature that we know: ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth space-time with the jittery world of quantum mechanics. A new wave of ...

Inside high-energy proton collisions, quarks and gluons briefly form a dense, boiling state before cooling into ordinary ...

WASHINGTON, Sept. 6, 2023 – Though a cornerstone of thermodynamics, entropy remains one of the most vexing concepts to teach budding physicists in the classroom. As a result, many people oversimplify ...

When the constant-depth circuit is removed, the value of topological entanglement entropy (γ) computed from the state returns to the ideal value (γ₀). Credit: Dr. Bowen Shi. In a new study, scientists ...

How can the strange properties of quantum particles be exploited to perform extremely accurate measurements? This question is at the heart of the research field of quantum metrology. One example is ...

Forgetting feels like a failure of attention, but physics treats it as a fundamental process with a measurable price. At the ...

By Partha Sinha Entropy fascinates because it announces itself. It spreads, decays and disperses. It makes noise. Like Kali, ...
