In a stunning leap for quantum optics, scientists have generated ultrafast light pulses whose quantum uncertainty can be ...

During the mid- to late-twentieth century, quantum physicists picked apart the unified theory of physics that Einstein’s theory of relativity offered. The physics of the large was governed by gravity, ...

“In a GHZ state, if you measure one qubit, the whole superposition collapses. But in a W state, even if you measure one ...

A hidden world of quantum metrologists ensure that everyday devices perform safely and correctly, but their work is never done ...

Uncertainty affects the accuracy with which measurements can be made in quantum physics. To reduce this uncertainty, physicists have learned to "squeeze" certain measurements. Researchers are now ...

Recently in my physics lab, students were having trouble with the difference between mass and weight. I had ready answers---it’s a topic I’ve gone over hundreds of times. But after I explained that ...

This morning on BBC Radio 4, the mathematician Roger Penrose, physicist Basil Hiley, and philosopher Simon Saunders had a lively discussion about the “measurement problem in physics” with broadcaster ...

New measurements of a subatomic particle provide the strongest hint yet that the leading theory of quantum physics that explains our universe may be missing a fundamental element, scientists say. The ...

Any exam preparation is a rigorous process which requires an overall understanding of the concepts and basics discussed in a chapter. If we talk about the Class 11 Physics, then one thing to be ...
