While usual gapless points that are not geometrically defective i.e. Dirac points (Left column) possess only eigenvalues within [0, 1] (Bottom Left), defective exceptional points (Right column) also ...

In recent years, there have been attempts to describe the inside of a proton using quantum information tools, with partial success. It has been discovered that quantum entanglement in the proton is ...

Physicists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and Stony Brook University (SBU) have shown that particles produced in collimated sprays called jets retain ...

Scientists have a new way to use data from high-energy particle smashups to peer inside protons. Their approach uses quantum information science to map out how particle tracks streaming from ...

Quantum entanglement lies at the heart of modern information theory, providing a non-classical resource that underpins quantum communication, computation and cryptography. Entanglement measures ...

Physicists developed simplified formulas to quantify quantum entanglement in strongly correlated electron systems. Their approach was applied to nanoscale materials, revealing unexpected quantum ...

While quantum entanglement mimicks the first law of thermodynamics in terms of entropy in a system, scientists wonder if the second law—especially the part about reversibility—could hold true. A new ...

Even if a version of the entanglement experiment is eventually carried out, it is important to be clear about what a positive result would mean. Observing entanglement between two masses that interact ...

A new study by Queen Mary University of London mathematician Professor Ginestra Bianconi proposes a new perspective on one of the deepest questions in modern physics: How can the universe become ...

A paper published July 16, 2026 in Physical Review D offers a mathematically precise resolution to one of physics' oldest irritants: the universe has been growing more disordered for 13.8 billion ...
