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 ...

In a stunning leap for quantum optics, scientists have generated ultrafast light pulses whose quantum uncertainty can be directly controlled and observed in real time. The achievement pushes the ...

What is the meaning of Heisenberg’s analogy? (Courtesy: German Federal Archives) A row has broken out among physicists over an analogy used by Werner Heisenberg in 1927 to make sense of his famous ...
