The road to quantum computing

Anticipating the advent of the quantum computer, related mathematical methods already provide insight into conventional computer science.

Atoms with quantum memory

Order tends towards disorder. This is also true for quantum states. Measurements at the Vienna University of Technology show that in quantum mechanics this transition can be quite different from what we experience in our ...

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 ...

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 ...
