Based on particles in a quantum state termed “Bose-Einstein condensate”, physicists from Argentina and Germany created for the first time a novel kind of sound laser, or “saser”. The experimental development represents a scientific breakthrough, and opens the way to applications in quantum computation, telecommunications, and health. Publication date: 09/11/2020 Bose-Einstein condensates (BECs) were first theoretically proposed by Satyendra Nath Bose y Albert Einstein almost a century ago. In 1995,…
