IIP-UFRN team publishes new article on quantum network testing in PRL

Published Tue, Sep 15, 2020
A new written work on quantum networks, developed by researchers from the International Physics Institute of UFRN and collaborators from other institutions, demonstrates the validity of restrictions on covariance observable in quantum networks. The article Semidefinite Tests for Quantum Network...

Black box physics

Published Fri, Sep 11, 2020
We have known since the 1960’s that quantum theory is incompatible with our most basic intuition about cause and effect relationships. More precisely, Bell's theorem shows us that correlations obtained by measurements in entangled quantum systems cannot be explained by any theory that...

LIGO / Virgo collaboration announces the detection of the largest black hole collision ever detected

Published Wed, Sep 02, 2020
On May 21, 2019, the Advanced LIGO and Advanced Virgo detectors observed a gravitational wave signal emitted from an extraordinary double black hole fusion. The signal, called GW190521, was the shortest and had the lowest frequency content ever detected. The time for which the signal is visible on...

Mathematical Structure of Particle Collisions Comes Into View

Published Thu, Aug 27, 2020
Recently published papers from a research group at the University of Padua (Italy) have revealed an underlying mathematical structure in the equations for models in particle physics. The work provides a new way of collapsing interminable terms into just dozens of essential components. Their method...
