World record for the entanglement of twisted light quanta

(Phys.org)—The Vienna research team led by Anton Zeilinger has achieved a new milestone in the history of quantum physics: The scientists were able to generate and measure the entanglement of the largest quantum numbers ...

Do measurements produce the reality they show us?

Whenever the precision of a measurement approaches the uncertainty limit defined by quantum mechanics, the outcomes of the measurement depend on the dynamics of the interactions with the meter used to determine a physical ...

Examining the origins of proton spin

Where does the proton get its spin? This question has puzzled physicists ever since experiments in the 1980s revealed that a proton's constituent quarks—the most fundamental building blocks of atomic nuclei—account for ...
