Reliably quantifying and characterizing the quantum states of various systems is highly advantageous for both quantum physics ...

"In quantum physics you can never actually have full information about a system. We can choose a property of the system that we want to measure -- a so-called observable. This can be, for example, the ...

Quantum physics isn’t just complicated – after 100 years, there is an awful lot of it to understand. This makes writing an accessible yet comprehensive book about the topic a challenge in both ...

It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is ...

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 ...

In addition, generalising the concept of an entanglement battery to a resource battery - an additional quantum system that participates in the transformation process without reducing the resource in ...

For bringing quantum effects to a scale once thought impossible, three physicists have won the 2025 Nobel Prize in physics. In the 1980s, John Clarke, Michel Devoret and John Martinis demonstrated the ...

The first step toward quantum gravity, the "holy grail of physics," may be hiding in a quantum recipe to cook up black holes. That's the suggestion of new research that adds quantum corrections to ...

If you asked a thousand physicists, they would all disagree. This statement could apply to any number of topics – whether the universe is infinite, what dark matter is made of, how to make wires ...

The 2025 Nobel Prize in Physics has been awarded to John Clarke, Michel H. Devoret, and John M. Martinis “for the discovery of macroscopic quantum tunneling and energy quantization in an electrical ...
