(Phys.org)—Any number can, in theory, be written as the product of prime numbers. For small numbers, this is easy (for example, the prime factors of 12 are 2, 2, and 3), but for large numbers, prime factorization becomes ...
University of Vienna research team has succeeded in breaking two novel records while experimenting with so-called twisted particles of light. These results, now published in the journal PNAS, are not only of fundamental interest ...

(Phys.org)—In order to determine how fast quantum technologies can ultimately operate, physicists have established the concept of "quantum speed limits." Quantum speed limits impose limitations on how fast a quantum system ...
Computers are a ubiquitous part of modern technology, utilized in smartphones, cars, kitchen appliances, and more. But there are limits to their power. New faculty member Fernando Brandão, the Bren Professor of Theoretical ...

(Phys.org)—It was another banner week for physics as one team at Cornell verified the 'Zeno effect,' whereby atoms won't move while observed. They conducted experiments in an Ultracold Lab and found that atoms that normally ...
(Phys.org)—In 1924, the mathematician David Hilbert described a hotel with an infinite number of rooms that are all occupied. Demonstrating the counterintuitive nature of infinity, he showed that the hotel could still accommodate ...
